Capitalization
Italicization Index   Plurals

Capitals are used for two broad purposes in English: they mark a beginning (as of a sentence) and they signal a proper noun, pronoun, or adjective. The following principles, each with bracketed examples, describe the most common uses of capital letters.

Beginnings

1.  The first word of a sentence or sentence fragment is capitalized.
< The play lasted nearly three hours. >
< How are you feeling? >
< Bravo! >
< ``Have you hand grenades?''
``Plenty.''
``How many rounds per rifle?''
``Plenty.''
``How many?''
``One hundred fifty. More maybe.''
- Ernest Hemingway >

2.  The first word of a sentence contained within parentheses is capitalized if it does not occur within another sentence; however, a parenthetical sentence occurring in the midst of another sentence does not begin with a capital.
< The discussion was held in the boardroom. (The results are still confidential.) >
< Although we liked the restaurant (their Italian food was the best), we seldom ate there. >
< After waiting in line for an hour (why do we do these things?), we finally left. >

3.  The first word of a direct quotation is capitalized; however, if the quotation is interrupted in the middle of a sentence, the second part does not begin with a capital.
< The President said, ``We have rejected this report entirely.'' >
< ``We have rejected this report entirely,'' the President said, ``and we will not comment on it further.'' >
NOTE: When a quotation, whether a sentence fragment or a complete sentence, is syntactically dependent on the sentence in which it occurs, the quotation does not begin with a capital.
< The President made it clear ``that there is no room for compromise.'' >

4.  The first word of a direct question within a sentence is capitalized.
< That question is: Is man an ape or an angel?
- Benjamin Disrael >
< My first thought was, How can I avoid this assignment? >

5.  The first word of a line of poetry is capitalized.
< The best lack all conviction,
while the worst
Are full of passionate
intensity.
- W. B. Yeats >

6.  The first word following a colon may be lowercased or capitalized if it introduces a complete sentence; while the former is the more usual styling, the latter is common when the sentence introduced by the colon is fairly lengthy and distinctly separate from the preceding clause.
< The advantage of this particular system is clear: it's inexpensive. >
< The situation is critical: This company cannot hope to recoup the fourth-quarter losses that were sustained in five operating divisions. >

7.  The first words of run-in enumerations that form complete sentences are capitalized, as are the first words of phrasal lists and enumerations blocked beneath running texts; however, phrasal enumerations run in with the introductory text are lowercased.
< Do the following tasks at the end of the day: 1. Clean your typewriter. 2. Clear your desktop of papers. 3. Cover office machines. 4. Straighten the contents of your desk drawers, cabinets, and bookcases. >
< This is the agenda:
Call to order
Roll call
Minutes of the previous
meeting
Treasurer's report  >
< On the agenda will be (1) call to order, (2) roll call, (3) minutes of the previous meeting, (4) treasurer's report. ... >

8.  The first word in an outline heading is capitalized.
< I. Editorial tasks
II. Production responsibilities
A. Cost estimates
B. Bids >

9.  The first word of the salutation of a letter and the first word of a complimentary close are capitalized.
< Dear Mary, >
< Gentlemen: >
< Sincerely yours, >
< Yours sincerely, >



Proper Nouns, Pronouns, and Adjectives

The essential distinction in the use of capitals and lowercase letters beginning words lies in the particularizing or individualizing significance of capitals as against the generic or generalizing significance of lowercase. A capital is used with proper nouns, that is, nouns that distinguish some individual person, place, or thing from others of the same class, and with proper adjectives, that is, adjectives that take their descriptive meaning from what is named by the noun.
