a, an
Use a before a consonant sound: a historical guide, a onetime king, a homage, a U-turn. Use an before a vowel sound: an onion, an 11-year-old child, an L-shaped structure. Before abbreviations, including acronyms, use a or an according to the pronunciation: an AWOL soldier, a GI.
Words with a voiced h are preceded by a (e.g., a historical guide); an unvoiced h takes an: heir, herb, honest, honor, hour. Most of the derivatives of these five also take an except for the derivatives of herb, most of which take a: an herb, a herbivore.
After a possessive, omit initial A or An of a title: Dickens's Tale of Two Cities, Ambrose Bierce's Occurrence at Owl Creek Bridge.
a-
Verbals like a-brewing are hyphenated unless one word in Webster's.
à la, à la carte, à la king, à la mode
Roman.

Academy Awards
Lowercase the academy and the awards when standing alone; no hyphens are required in name of award: best actress award. Also known as the Oscars.
ACCENT MARKS
Follow Webster's.
Foreign terms that have not become anglicized should be set in italics on first use and given proper accents if from a Latin alphabet. A word may become roman and still keep its diacritical mark: mañana. Anglicized words may be italicized on occasion to emphasize their foreign flavor: mañana, kat.
Place-names from foreign languages appear in roman; retain diacritical marks if original is from a Latin alphabet except in commonly anglicized names: Montreal, Quebec, Istanbul. If a place-name is transliterated from a non-Latin alphabet, diacritical marks are generally not used except on atlas and supplement maps. Place-names from Arabic or Cyrillic follow the common anglicized spellings. Follow NGS atlas, then the Board on Geographic Names.
Languages with Latin alphabets: Retain the original diacritical marks (accents, apostrophes, dots, cedillas, glottals, etc.) in unanglicized words in the following languages: Czech, Danish, Dutch, Finnish, French, German, Hawaiian, Hungarian, Icelandic, Irish, Italian, Latvian, Norwegian, Polish, Portuguese, Slovak, Spanish, Swedish, and Turkish. Some anglicized terms from these languages also retain their accents (follow Webster’s).
Modern style is to retain accents on French capital letters, especially in French place-names, as in Île de la Cité. The word à does not carry an accent when capitalized.
In Spanish retain accents on capital letters.
Use accents on American Indian words as well as on words of other indigenous peoples if the language is written in the Latin alphabet.
Although Vietnamese is written in the Latin alphabet, the number of accent marks can be distracting and may therefore be omitted.
Commonly used diacritics:
The diaeresis is being dropped, though classical names and a few others still retain it: Laocoön, Brontë, the opera Aïda.
Languages with non-Latin alphabets: Do not use diacritical marks for place-names in magazine text or on page maps even if they appear on supplement maps or in the atlas. However, place-names in the text of a supplement map itself should follow the map spelling, including the use of diacritical marks. Non-Latin scripts do not equate letter for letter with English; different authorities use different systems of transliteration. Consult an authority. The preference of the individual should control the anglicizing of a personal name. The following languages are among those that do not have Latin alphabets: Arabic, Bulgarian, Chinese, Georgian, Greek, Hebrew, Japanese, Korean, Russian, Serbian.
See also Chinese Names and Terms, Diacritical Marks, and Russian Language.
according to
This phrase is a preposition and does not require a comma when used at the beginning a sentence: According to Mickey Sweeney commas should be used sparingly. However, when the introductory phrase is long, a comma may be used.
accord, accords
Capitalized in formal or accepted titles of agreements such as: Helsinki Accords, Dayton Peace Accord, Plaza Accord, the Accord of Winchester; otherwise lowercase: Camp David accords, the Israeli-PLO accord, Meech Lake accord (unratified), a 1991 peace accord, the accords.
ACRONYMS
Except when they have entered the language as words (radar, flak, Anzac), acronyms are in full caps, no spaces or periods. Long acronyms may be reduced in type size for the sake of appearance. Use a or an according to the pronunciation: an AIDS researcher, a UNESCO program. Plurals add lowercase s: WASPs.
act
the second act; Act 2, Scene 2
acts and laws (federal, state, or foreign)
A bill passed by Congress becomes an act or law. Capitalize when the official title is given, when using a title by which an act or a law is most commonly known, or when numbered. But lowercase act or law when it stands alone or in shortened titles or general descriptions.
|   | Atomic Energy Act or McMahon Act, the act
Smoot-Hawley Tariff Act; the tariff act; the act
Federal Housing Act of 1961; the housing act of 1961; the 1961 act
Immigration Reform and Control Act (IRCA)
Sherman Antitrust Act; the antitrust act; the act
Social Security Act
Walsh-Healey Act
Act of Toleration
act of Congress, the act
Public Act 26; Public Law 9
Multiple Dwelling Law, the law |
A.D.
Small caps, periods, no space. A.D. precedes the year but follows the century. Use only in early dates when the era might be in doubt. Though A.D. means "in the year of the Lord," supply the pertinent English preposition; do not add the word "year":
|   | Pompeii was buried August 24, A.D. 79; around A.D. 79
Augustus died in A.D. 14; not in the year A.D. 14
He died in the first century A.D.
June, A.D. 52
A.D. 300 to 1000
100 B.C. to A.D. 50 |
An alternative system gaining popularity, especially in academic literature, uses C.E. (meaning the Common Era and used in place of A.D.) and B.C.E. (before the Common Era). National Geographic generally uses the traditional terms, A.D. and B.C.
See also B.C.
ADDRESSES, URL (abbreviation for uniform resource locator)
Use italics for an internet address (URL) in text and legends: nationalgeographic.com/celebrate.
In boilerplates and display type URLs are generally set in the same typeface as adjacent words: For Member Services: ngmservice.com.
Do not use a hyphen or other punctuation when breaking an electronic address or URL at the end of a line. If an address contains a hyphen, do not break the address at the hyphen. If breaking the address at a period, put the period on the next line so it will not be read as the end of a sentence. Use normal punctuation at the end of the address if it completes a sentence.
A space in an address is indicated by underlined space.
When using three dots with a partial address, put spaces between each dot and between what comes before and after the dots: See . . . /features/97/wave.
ADJECTIVES AND ADVERBS, PUNCTUATION OF
When two or more modifiers precede a noun, a comma, no punctuation, or a hyphen may be appropriate.
| 1. Comma: | Use a comma when two or more modifiers before a noun can trade positions with relative ease or when you can easily insert and between the adjectives: |
 
|   | the cheerful, busy children | the busy, cheerful children |
 
|   | When one of the modifiers explains, amplifies, or partly contradicts an earlier modifier, use commas: my samloh, or pedicab, operator. Do not put a comma after the final modifier simply because it has a modifier itself: men of that dim, often frigid past. |
 
| 2. No Punctuation: | Use no punctuation when two or more modifiers before a noun are fixed in their relative positions and all modify the noun directly: traditional political institutions; a severe tropical storm. When in doubt, omit the comma. |
 
| 3. Hyphen: | Use a hyphen when two or more modifiers link to form a single concept that precedes a noun. If one of the modifiers is itself a compound, an en dash may be used instead of a hyphen. |
 
|   | a calf-size dog
a two-for-one bargain
iron-and-steel mill | a two-act comedy
iron- and steelworks
Civil War era houses |
|   | low- to high-income housing
forest- and bush-loving antelope
nuclear-armed and nuclear-powered ships not
  nuclear-armed and -powered ships |
Punctuation can influence the meaning: red, white, and blue flags (solid-colored flags), red-white-and-blue flags (tricolors). Do not hyphenate compound color modifiers unless hyphenated in Webster's or both elements are colors of equal value: blue-black sky, gray-green eyes, but bluish black sky, lemon yellow dress, jade green lake, cobalt blue dish. To avoid ambiguity, note: light-blue suit (color), light blue suit (weight).
Adverbs that end in -ly are not hyphenated: faintly heard call. A three-word modifier, the first of which is an adverb ending in -ly, need not be hyphenated unless ambiguity results: freshly laid out linen, newly set aside parklands. There are a number of adverbs that look like adjectives because they do not end in -ly. Of these, compounds with dead, long, near, and well are generally hyphenated before a noun: dead-tired feet, long-established use, near-realized hopes, well-dressed man.
Unless the meaning is ambiguous or a compound is hyphenated in Webster's, do not hyphenate compounds with almost, already, best, early, ever, last, late, less, more, most, much, never, not, now, once, only, seldom, sometimes, still, very, yet. See even. Consult Webster's, especially for compounds with over and under.
Do not hyphenate:
|   | a) | a compound modifier before a noun when the compound itself carries a modifier or after a noun unless subject to misreading or hyphenated in Webster's as an adjective: |
 
|   | a well-built house
a house well built | a very well built house
the house was well built |
 
|   | b) | a compound proper noun used as an adjective. Hyphenate, however, a prefix before a capital letter, or when hyphenated in Webster's: |
 
|   | New York skyline, but New York-born man or New York born man
South American countries
Latin American ways (NGS preference)
San Francisco area resident
Old English customs
pre-Columbian vase
un-Burgundian ways |  |
 |  |  |
 
|   | c) | foreign terms: bona fide friends, a de facto peace, per capita income, status quo policy, but laissez-faire policy. |
 
|   | d) | chemical terms used as compound adjectives except if ambiguous or when used with the mass number: carbon dioxide test, but carbon-14 dating; iron-oxide red; strontium-90, strontium-90 fallout. |
 
|   | e) | widely used compound nouns appearing in Webster's when they are used as adjectives, such as bald eagle, foreign exchange, income tax, and real estate, except where misreading could result and a hyphen helps readability. |
 
|   | f) | a two-word modifier when the second word is a possessive: history teacher's papers, a planning council's decision. |
 
|   | g) | ordinals with comparatives or superlatives: second largest producer, third longest tunnel, first ever study, but first-grade potatoes, second-class citizens. |
 
|   | h) | compound modifiers with comparatives or superlatives unless subject to misreading: more favorable weather, earliest known city, lesser known novel, best loved story, but best-selling novels, worst-case scenario. |

African, African American, Afrikaner, black, Coloured, colored, native, Negro
| 1. | Africa: Usage varies; when there is doubt, consult an expert. The nationality (such as Libyan or Egyptian) or the ethnic group (such as Arab, Hamite, or Copt) may be used. The general range of the ethnic group may be indicated, such as European, Asian, Indian, etc., for nonblack people.
Blacks are called blacks or Africans. The term Negro may be applied in referring to the black or Negroid races. The area in which they live may be called black Africa.
The term native may give offense.
In South Africa those of Dutch, German, and French Huguenot descent are called Afrikaners (and speak Afrikaans); there is no general term for English-speaking whites. Blacks are called blacks, and those of mixed blood are known as Coloureds, not Cape Coloureds as formerly.
|
| 2. | United States: Do not use colored in present-day U.S. context. Use black (noun and adjective) or African American (noun) and African-American (adjective) in preference to Negro: the blacks of Los Angeles, the black doctor.

AGREEMENT, SUBJECT-VERB
Verbs must agree in number with the subject. The following are particularly troublesome constructions:
All
All is singular when used as the subject with a linking verb or when it means the only thing or everything: All I want for Christmas is my two front teeth; all we found was candy wrappers and soda cans. All may take a plural verb when the context is plural, often indicated by a prepositional phrase: All of us are happy to be here.
Along with, as well as, plus, together with
These phrases used after a singular subject, and often set off by commas, do not change the singular verb: John, as well as Jane, is here; unemployment plus poverty breeds anger. But note, a compound subject joined by and in which the writer chooses to set off the second element with commas still takes a plural verb: John, and his sister, are officers in the company.
Anyone, each, either, every, everyone, many a, no one, nothing, someone, something
All these indefinite pronouns require singular verbs: Each has his point of view; everyone is welcome; nothing can be done.
Collectives
Collectives (family, team, couple, etc.) are plural when the component members are considered separately and singular when the group is handled as a unit: a score were present; an army marches on its stomach. The plural prevails when humans are concerned: The couple are. . . . The decision between singular and plural is frequently writer’s choice. Once the number is established, be consistent: My family trusts only people it knows; my family trust only people they know.
Compound Subject
Two subjects connected by and usually require a plural verb: Experience and education are necessary. However, if the compound subject is considered as a unit, the verb should be singular: Bacon and eggs is his favorite breakfast; but bacon and eggs are among his least favorite foods. Sometimes an author will for emphasis separate the second element of a compound subject with commas. This is not the same as using along with and still requires a plural verb: John, and his sister, are officers in the company.
Measurements
Generally a number, fraction, or quantity of things is considered singular if considered as a mass (ten gallons is enough) and plural if considered as separate units (ten dishfuls were slowly doled out). Sums of money, time, distances, and other similar measurements are often singular (Only years of dedication earns a climber the right to stand on such a peak).
None
May take either a singular verb (when it means not one) or a plural verb (when it means not any), but plural is more common: None were up at 7 a.m.; none of it was taken; none of them were here.
One of . . .
This phrase usually is followed by a plural noun, which requires a plural verb: He is one of the men who have risen quickly to the top; she is one of those people who get things done.
Or
In a compound subject joined by or, the verb agrees with the final member: Wine or cocktails are served; soft drinks, cocktails, or wine is served.
AIDS
May be used without defining as acquired immune deficiency syndrome.
See HIV/AIDS.
Air Base
Capitalize when part of the name for U.S. air base abroad: Rhein-Main Air Base. Use Air Force Base in U.S. or possessions: Scott Air Force Base, Illinois, the Air Force base, the air base, the base.
AIR FORCE
Capitalize when preceded by name of country or when name is well established: United States Air Force, Royal Air Force (RAF), French Air Force, Soviet Air Force, etc.; capitalize the Air Force in subsequent references to the U.S. Air Force (which was preceded by the United States Army Air Forces), the Air Force (USAF), but lowercase such references to any foreign air force. Spell out and capitalize units of the U.S. Air Force through Tenth: Fifth Air Force, 11th Air Force, 474th Fighter Wing.
For Air Force ranks and abbreviations see Military Ranks.
air kissing
air traffic control, air traffic controller
AIRCRAFT
Use italics for names of planes, balloons, gliders, etc.: the Spirit of St. Louis, Double Eagle II. Types of planes are roman with initial caps: Piper Cub, Learjet, Flying Fortress. Planes with numbered or lettered designations form plurals with s, no apostrophe: C-54s, F-6Fs, 707s, Cessna 185s, MiGs. Maker's name need not be given.
See also Space Terms.
airman

Write lowercase and without periods the abbreviation for also known as.
Akhenaten
The correct division of syllables is Akhen aten.
Aten is the word for the sun god and should be kept intact.
Al Jazeera
Arabic-language television news network based in Qatar.
al Qaeda
Alaska
The continental United States includes Alaska. In Alaska context, lower forty-eight or lower 48 may be used. Do not hyphenate lower 48 as an adjective. The term outside may be put in quotes on first reference if ambiguous. To distinguish the 48 states from the 49 or 50, use contiguous or conterminous.
Alaska native means one of the native peoples, i.e., Indian, Aleut, Eskimo. A native Alaskan means any person born in Alaska.
NGS-preferred adjective is Alaska: the Alaska seacoast is extremely rugged; the Alaska economy is stagnant.
albatross, albatrosses
NGS preferred plural.
alga, algae
Alga is the singular noun and requires a singular verb: A colony of Licmophora fans itself across another alga, Bonnemaisonia. Algae is the plural form and requires a plural verb: When the algae die, they fall to the bottom.
Occasionally algae may be considered a collective noun and treated as singular: A map shows how algae periodically blooms in the bay. Look! There it has drifted under the bridges, and out into the ocean, where it hovers over the reef.
Algal is the adjective: Red indicates unusually high algal growth.
Algonquin
An American Indian people of the Ottawa River Valley of Quebec and Ontario. Use Algonquian for the vast language group of associated tribes stretching from Carolina to Labrador.
all
When used as the subject with a linking verb, all is usually singular. (Theodore Bernstein notes that when all means the only thing or everything, it is singular.) Note in the last two examples that the singular regulates both the subordinate and main verbs:



All I want for Christmas is my two front teeth.



All we found was candy wrappers and soda cans.



All that’s left of the structure is oak footings.



All that remains of the Hejaz Railway is scraps of rusty iron.
All may take a plural verb when the context is plural, often dictated by a prepositional phrase:



All of us are happy to be here.



All the books were saved from the fire.



All were happy to serve on the jury.
Generally omit of when all is followed by a noun:



He ate all the cake, but he ate all of it.
all-
Hyphenate in a compound modifier before and after a noun.
all right
Not alright.
all together, altogether
All together means as a group: All together they weighed 40 pounds, we found the books all together or we found all the books together. Note: All together can only be used if it is possible by rephrasing to separate all and together.
Altogether means entirely: The trip was altogether worthwhile, altogether the United States uses 339 billion gallons of water each day.
As a noun, one's birthday suit, presumably all in one piece, uses altogether: The Style Committee refused to pose in the altogether (meaning nude: note "the").
Allah akbar
The Islamic call to prayer is transliterated from written Arabic as Allah akbar and is generally translated "God is great," though it can also be translated "God is greater," "God is most great," or more loosely, as our Turkish partners do it, "Allah the Almighty." When spoken, an additional syllable appears between the two words, which can be rendered Allah-u akbar, but unless stressing pronunciation, NGS style prefers Allah akbar.
Allied, Allies
Capitalize in context of World War I or II: Allied powers, Allied forces, the Allies defeated Germany, but the U.S. and its allies in World War II.
almost
Not hyphenated in compound modifiers.
along with
Followed by singular or plural verb depending on subject: Ted along with Mary and Sue works late; Mary and Sue along with Ted work late.
Alpine, alpine
Capitalize in context of the true Alps: Alpine plants, Alpine peaks, Alpine skiing (regardless of where event is held), etc. Lowercase in other uses: alpine plants of Colorado.
already
Not hyphenated in compound modifiers.
also known as
May be abbreviated in lowercase without periods: aka.
Altiplano
Capitalize for region of South America shown in NGS atlas; otherwise lowercase.
a.m.
Lowercase, periods, no space. Use figures with this term: 3 a.m., but three o'clock, twelve o'clock; the 4 a.m. bell (no hyphen). Write noon or midnight, not 12 a.m. or 12 p.m.
ambassador
Never abbreviate. Capitalize before personal name or when linked to both name and country: Ambassador Bellows; Melina Gerosa Bellows, Ambassador to Egypt; our ambassador to Egypt; the Egyptian ambassador; the ambassador.
Amendment (U.S. Constitution)
Spell out through Tenth Amendment. An enacted and ratified amendment is capitalized when its number is used: the Fifth Amendment, the 18th Amendment. Lowercase informal titles unless they include words that are capitalized in their own right: income tax amendment, the Prohibition amendment. A proposed constitutional amendment should be lowercase: equal rights amendment (ERA), the Bricker amendment.
America, American
In reference to matters having to do with the United States, NGS preference is to use United States or U.S. as both noun and adjective whenever possible, to avoid excluding
and offending
Canadian and Latin American readers: chief United States export. However, the use of America and American in reference to the United States and its citizens is well established and not incorrect.
America Online, Inc., AOL
-American
Do not hyphenate as a compound proper noun:
|   | African American | Mexican American | Irish American |
Hyphenate, however, as a compound proper adjective unless the term reflects a geographic place-name:
|   | Polish-American influence
North (South, Central) American culture | Japanese-American art
Latin American businessman |
American Indian Movement
AMERICAN INDIANS, NORTH AND SOUTH
The terms American Indian, Indian, and Native American are all acceptable and can be used interchangeably, although Native American, a broader term, may include Aleuts and Eskimos. Be sensitive to individual preference when using these terms and whenever possible use a specific group or tribal name.
For a specific group follow the spelling in Webster's or the Style Manual. For tribal plurals do not add s: Comanche, Cuna, Shoshone, Aztec, Maya; for individuals, s may be added: three Comanches. But a Blackfeet, the Blackfeet nation, the Blackfeet in U.S. context.

amid
Not amidst.
among, between
Among is normally used with more than two things: the four shared it among themselves. Between is used with two; it also may be used with more than two to suggest an individual relationship one to the other: a treaty between three powers.
ampersand (&)
Avoid except when used by organization on its letterhead: AT&T, C & O, Texas A&M, etc.
Anasazi
Singular and plural. The Navajo term archaeologists use to distinguish the early peoples of the ancient pueblos and now variously translated as "alien ancient ones," "ancient ones," "ancient enemies," or "ancestors of people other than our own," i.e., the ancestors of non-Navajo. Some modern Pueblo Indians (the descendants of the Anasazi) consider the term derogatory and prefer ancestral Puebloan or ancient Pueblo people.
Anchor fence
Trade name. Generic term is chain-link fence.
ancient, old
In a strict sense ancient means no later than the traditional end of the Roman Empire (A.D. 476) or, in the Western Hemisphere, no later than Columbus's discovery. However, in a more general sense ancient may be used as a synonym for old. Let context determine how strict to be.

Lowercase: the archangel Gabriel.
ANIMALS
Refer to an animal as it, unless sex is known; generally avoid using who with animals.
As a general rule, for breeds of animals capitalize any part of the name that derives from a proper noun: a Boston bull, the Holstein cow, a Black Angus, but arctic hare, etc. Names given to pets or wild animals take initial caps and no quotes: Mary Crocodile, Koko. Lowercase numbered groups or individuals: group 817, male 204, herd 111, bull number 55.
Animal sounds and bird calls are italic, no quotation marks; for plural add roman s to the italic word and apostrophe: the black-and-white male's dreo, dreo, dreo mating call; hoo's; high-pitched whoo-ing call.
See also Breeds, Names (section 4), and Scientific Nomenclature.
Annan, Kofi
Former Secretary-General of the United Nations Kofi Annan.
Antarctic
Capitalize as geographic feature; lowercase plants and animals listed in Webster's:
|   | Antarctica
Antarctic Circle
Antarctic Peninsula
Antarctic continent
Antarctic coast
but antarctic beech | Antarctic life
Antarctic snow
Antarctic wastes
Antarctic waters
Antarctic scientist |
Antarctic Convergence, Antarctic Polar Front
Use Antarctic Convergence for the region about a thousand miles off the Antarctic coast where cold waters meet warmer waters from the north. Some scientists use Antarctic Polar Front as a synonym, but that term is not as familiar and could be confusing since it can also refer to a meteorological event.
Antarctic Ocean
The National Geographic does not recognize this place-name. Though the waters surrounding Antarctica are sometimes called the Antarctic Ocean or Southern Ocean, they are only the southernmost parts of the Indian, Pacific, and Atlantic Oceans.
See also Southern Ocean.
antenna, antennae, antennas
antennae: biological reference
antennas: aerials
anthropomorphism
Be cautious in applying human attributes to other animals. Saying that salmon is a bear’s favorite food implies likes and dislikes and is not the same as saying salmon is a bear’s main food. Saying an iguana loves to sit on a warm rock is not the same as explaining the biological reasons for such behavior. On the other hand, recent scientific research has shown that some animals may indeed have feelings, and scientists themselves sometimes use anthropomorphic language to describe animal behavior, especially in highly intelligent mammals. Used with discretion, anthropomorphism may help tell a story and accurately convey information to a lay reader.
anti-
If not in Webster's, hyphenate this prefix before i and capitalized words or when a hyphen will improve readability:
| | anti-Catholic
anti-intellectual | anti-egalitarian
anti-Irish |
| | but Anti-Federalist (historical usage) |
antivenom
NGS prefers antivenom to antivenin. Exception to Webster's.
Antony, Mark
NGS preferred spelling for Marcus Antonius.
anymore
One word as adverb; use only in negative or conditional context or in a question. Use any more only when more alone makes sense: Don't give me any more liver.
anytime
Spell the adverb as one word when replaceable by the phrase at any time; when it cannot be, use as two words: The meeting can be scheduled anytime, but I will not have any time for it.
AOL Keyword
Capitalize Keyword when used in the phrase AOL Keyword. The Society keyword is NatGeo. The magazine's keyword is NatGeoMag.
Apostle
Capitalize in biblical context:
|   | the Twelve Apostles, the Apostles
the Apostle Paul, the Apostle
the Apostles' Creed
an apostle of peace
Paul the Apostle |
APOSTROPHE
Plurals of abbreviations without periods and of figures are generally formed with s, no apostrophe. For abbreviations with periods and letters of the alphabet used as nouns, add apostrophe plus s. If double s combinations occur, add apostrophe plus s. Plurals of italicized letters add italic apostrophe plus roman s.

APPELLATIONS AND EPITHETS
Generally capped and not quoted if well established: Abe Lincoln, the Great Emancipator; Jenny Lind, the Swedish Nightingale. If less well established, lowercase within quotation marks: Perle Mesta, "the hostess with the mostest," Teddy considers himself the "bull of the woods." His reward was to be dubbed "his rotundity."
See also Nicknames.
APPOSITION
Words in nonrestrictive apposition are set off with commas; those that restrict preceding material are not.
| 1. | Nonrestrictive apposition merely adds information to something already identified: John's play, Phalanges, was a flop. (John wrote only one play.)
|
| 2. | Restrictive apposition completes the identification: Shakespeare's play Macbeth is on the reading list (one of many plays by Shakespeare).
|
| 3. | Relationships take commas or not depending upon how many relatives of the same kind there are. If there is but one, use commas: my wife, Nellie, and my son, Bob, came too (only one wife and only one son); Bob and his wife, Ann; but Bob and wife Ann. If there are two or more, no commas: her sister Millie and her cousin Karen came too (more than one sister and more than one cousin). |
Aqua-Lung
trade name
aquanaut
Lowercase: aquanaut Elaine Bradley.
Arabian Gulf
The internationally accepted name is Persian Gulf, although Arab countries call the body of water the Arabian Gulf. Where scale permits, National Geographic maps include a map note about the Arabian Gulf. (Note that this treatment supersedes that found in the eighth edition of the world atlas.) If Arabian Gulf is used in text, it should be explained. Do not capitalize states in Persian Gulf states.
Arabian Nights
Initial caps, roman; italic when book is meant.
Harun al-Rashid of Arabian Nights fame
I conjured up scenes from the Arabian Nights.
These customs flavor the fables in Arabian Nights.
The palaces looked like Arabian Nights creations.
The Arabian Nights fortress that guards the bay
ARABIC LANGUAGE, TRANSLITERATION OF
Place-names: Well-known place-names follow the common anglicized spellings; follow NGS atlas, then the U.S. Board on Geographic Names. Omit diacritical marks in text and on page maps though they appear on atlas and supplement maps. For hyphens with compound place-names, follow the NGS atlas; if the place-name is not in the atlas, omit hyphens both on page maps and in text. Al, El, or other articles should be used without hyphens and capitalized at the beginning of a name but lower cased in the middle: Al Karak, El Gezira, Kafr el Sheikh.
Personal Names: Do not use diacritical marks. The preference of the individual should govern the anglicized spelling of a personal name.
arch
Forms one-word compounds if not in Webster's, but hyphenate with a proper name: archconservative, arch-Republican.
archaeology
ARCHITECTURE
Capitalize the name of an architectural style when it derives from a proper noun; otherwise, lowercase: Corinthian, Doric, Gothic, neo-Gothic, high Gothic, Ionic, Romanesque, Early American, Greek Revival, etc., but art deco, baroque, classical, colonial, federal, rococo.
Arctic
Capitalize as geographic feature. Strictly speaking, Arctic refers to the region north of the Arctic Circle, though the term "Arctic region" can be used to include nearby areas of the subarctic. Lowercase plants and animals found in Webster's:
|   | Arctic Circle
the Arctic
Arctic Ocean
high Arctic
Arctic region
Arctic zone | Arctic boots
Arctic life
Arctic coast
Arctic scientist
eastern Arctic town

hare, wolf

When army is used by itself, capitalize in references to the U.S. Army, but lowercase such references to any foreign army. Spell out units through Tenth.
|   | United States Army, the Army, Army officer
the 19th Army, the army
the Indian Army, the army, army officer
Red Army, the army
Union Army, Grant's army, Confederate Army

ARTICLE REFERENCES
References to articles in previous issues or to another article in the same issue are usually given within parentheses in the text. Generally follow the title given in the National Geographic Index or on the article's title page, not the title on the cover or on the contents page, when they differ. Follow the punctuation of the running foot if there is one. If more than one article is cited, give the most recent article first, unless they should be read in a different order for better understanding: 
|   | The Stilwell Road was finished only months before the war ended. (See "Burma Road," November 2003.)
Mike Fay trekked from Congo to the Gabon coast (see the October 2000, March 2001, and August 2001 issues).
I had already found several burial sites carved into a cliff, including one prepared for a top official of Ramses the Great (see "A Pharaoh's Peacemaker," October 2002) and another belonging to a woman named Maia.

as well as
As a preposition this phrase means "in addition to" or "besides" and usually takes a gerund: She spends time in the laboratory as well as teaching three classes a week. As a conjunction, it means "and in addition" or "and not only" and needs parallel construction: She teaches as well as researches. A phrase beginning with "as well as" after a singular subject does not change the singular verb and is often set off by commas: John, as well as Jane, is . . . .
Asante
Preferred to Ashanti as NGS spelling.
Ascension
Capitalize when meaning the ascent of Christ into heaven.
Asian
Asian is preferred to Oriental and Asiatic as both noun and adjective. Not Asiatic in reference to a person, but Asiatic lion.

Assure means to promise or remove doubt; ensure, to make certain; insure, to guarantee by contract.

Use asterisk (*), dagger (
), double dagger (
), and section mark (§), in that order, for footnotes.
These marks, in text, follow all marks of punctuation except the dash or sometimes the parenthesis.
Regardless of where the asterisk falls on the page, the footnote, with rare exceptions, should go at the bottom of the last column of text.
Try to avoid using an asterisk or a footnote in the first or last column of an article.
Editor's, author's, and photographer's notes are not cued to an asterisk in the text.
