Follow the guidelines below in deciding when to capitalize the initial word in a word group.
Capitalize the first word of a sentence or sentence equivalent:
Capitalize the first word of a direct quotation that is itself a complete sentence:
Do not use the upper case if the quotation is merely a sentence fragment or is worked into the structure of the sentence:
In quotations where historical, legal, documentary or scientific accuracy is crucial, reproduce upper case letters as faithfully as possible.
Capitalize the first word of a complete sentence enclosed in parentheses when it stands alone, but not when it is enclosed within another sentence:
Capitalize the first word of a direct question within a sentence:
Consistently capitalize (or lower case) parallel sentence fragments used as questions:
Do not capitalize words that normally introduce questions (who, why, when, how) when they stand alone as verb complements:
Capitalize the first word after a colon if it begins a direct question (see above) or a formal statement, introduces a distinct idea, or is followed by more than one sentence:
The word following a question mark or exclamation mark may or may not be capitalized, depending on how closely the material it introduces is considered to be related to what precedes:
Capitalize the first words of truisms and mottoes run into text:
The personal pronoun I and the vocative O are always capitalized in English; oh is capitalized only when it begins a sentence or stands alone.
The first word of a line of poetry is traditionally capitalized, but some modern poets do not follow this practice. It is therefore best to check the original and respect the poet’s preference.
