Elementary Rules of Usage

Selected tips from Elements of Style by William Strunk Jr. and E.B. White, presented without commentary:

• Form the possessive singular of nouns by adding 's.
• In a series of three or more terms with a single conjunction, use a comma after each term except the last.
• Enclose parenthetic expressions between commas.
• Place a comma before a conjunction introducing an independent clause.
• Use a colon after an independent clause to introduce a list of particulars, an appositive, an amplification, or an illustrative quotation.
• A participial phrase at the beginning of a sentence must refer to the grammatical subject.
