Rule 1.—The first word of every sentence should begin with a capital letter.
A sentence preceded by an introductory word or clause such as Resolved, Be it enacted, etc., begins with a capital notwithstanding the introductory word.
Rule II.—The first word of a direct quotation, of an important statement, and of a direct question, should begin with a capital.
Examples:
One truth is clear: Whatever is, is right.—Pope. Ask yourselves this question: Are you doing right?
Rule III.—The first word of every line of poetry should begin with a capital.
Rule IV.—All proper names begin with capitals. If the proper name consists of several words, all are capitalized except articles, prepositions, and conjunctions.
Examples:—San Diego, Burton-on-Trent, the Grand Army of the Republic.
The words street, road, lake, river, mountain, etc., should begin with capitals when used in connection with proper names.
Examples:—Crawford Road, Prospect Street, Lake Erie, Cuyahoga River, Little Mountain.
