The colon ( : ) is a mark of punctuation used after a statement (usually an independent clause) that introduces a quotation, an explanation, an example, or a series.

In addition, the colon usually appears after the salutation of a business letter (Dear Professor Legree:); between the chapter and verse numbers in a biblical citation (Genesis 1:1); between the title and subtitle of a book or article (Comma Sense: A FUNdamental Guide to Punctuation); and between numbers or groups of numbers in expressions of time (3:00 a.m.) and ratios (1:5).

From the Greek, "a limb, the mark ending a clause"

  • Colons, Semicolons, Commas, and Dashes
    - "Mandela understood the ties that bind the human spirit.

    (Kingsley Amis, "Delivery Guaranteed," 1979)
  • Using the Colon for Emphasis
    "The colon seems an unlikely candidate for dramatic effect, but now and then it serves that purpose well: Smith had only one passion: pornography of every sort."
    (Rene J. Cappon, The Associated Press Guide to Punctuation. Basic Books, 2003)
  • Multiple Meanings of Colons
    "A colon can be used to smooth over a rough logical connection. It has a verbal content ranging anywhere from 'namely' to 'thus,' and it can function to let the writer off the hook."
    (Paul Robinson, "The Philosophy of Punctuation," in Opera, Sex, and Other Vital Matters, 2002)
  • Capital Letters (or Not) After Colons
    - "Note that what comes after the colon is not usually a sentence itself—a point on which colons differ from semicolons. Style manuals agree (Chicago Manual, 2003; Oxford Guide to Style, 2002) that the word following the colon stays in lower case, unless it's a formal quotation, slogan or motto. For example:
    On the laboratory door was a new sign: Trespassers prosecuted.
    The word following a colon in the subtitle of a book or article may be capitalized."
    (Pam Peters, The Cambridge Guide to English Usage. Cambridge University Press, 2004)

    - "[S]hould we use a capital letter after the colon? With quotations and direct speech, as we see, the answer is yes. It's yes also if what follows the colon is a series of sentences:
    Two things would follow: First, the rivers would overflow.
    Second, the low-lying villages would be flooded.
    Showing that the sentences are parallel is felt to be the more important issue: both sentences relate back to Two things.
    (David Crystal, Making a Point: The Persnickety Story of English Punctuation. St. Martin's Press, 2015)
  • Colons for the Young and Old
    "When we are very young, we tend to regard the ability to use a colon much as a budding pianist regards the ability to play with crossed hands: many of us, when we are older, regard it as a proof of literary skill, maturity, even of sophistication: and many, whether young, not so young, or old, employ it gauchely, haphazardly or, at best, inconsistently.”
    (Eric Partridge, You Have a Point There: A Guide to Punctuation and Its Allies, rev. ed. Routledge, 1978)
  • Two Pricks
    "A pause is a distinction of a sentence, though perfect in itself, yet joined to another, being marked thus with two pricks (:)."
    (Ben Jonson, The English Grammar, 1640)
