Colons, Semi-Colons, and Dashes COLONS: 1. Separate two main clauses in which the second clause amplifies or explains the first. This dictum is often believed to be in the Hippocratic Oath: first, do no harm. 2. Introduce a series, quotation, or list. When using a colon to introduce a list, look for anticipatory phrases like thus, as follows, or the following. The words of Martin Luther King, Jr. became a popular theme for this year’s conference: “Are you able to accept blows without retaliation?” The parade included the following components: several floats, a large mechanized dragon, and enough cotton candy to feed a small army. 3. Separate elements. Use a colon to separate elements in the salutations of formal letters, ratios, biblical chapters and verses, titles and subtitles, and bibliographic information on cities and publishers. Dear Mr. Smith: New York: St. Martin’s, 2018. SEMI-COLONS: 1. Join separate independent clauses in a compound sentence when no connective word is used. In most cases, you can alternatively use a period and form two individual sentences. You should never use a semicolon to connect an independent clause and a dependent clause; use a comma instead. The sky was blue; the grass was green. 2. Connect main clauses joined by a conjunctive adverb or a coordinating conjunction. Conjunctive adverbs include also, besides, furthermore, then, however, thus, hence, indeed, and yet. Coordinating conjunctions include and, but, or, for, and nor.

DASHES: 1. Insert a comment into your sentence. The pleasures of reading itself—who doesn’t remember?—were like those of a Christmas cake, a sweet devouring. – Eudora Welty 2. Emphasize explanatory material. This emphasis can occur in the middle of the sentence—like this set of dashes is doing right now—or at the end of a sentence. The significance of kinship relationships in eighteenth-century England is often ignored by historians—except those who look at primary sources from the period. 3. Mark a sudden change in tone or indicate a hesitation of speech within a sentence.

Introduce a summary or explanation for your sentence.
