Often confused with cannon

16 meanings of canon

Practice

  1. 1
    classic worksnouncountable or uncountable
    The body of works accepted as the most important in a field, or as genuinely written by a particular author.

    Critics have argued for decades over which novels belong in the canon.

    The canons of philosophy and of literature overlap more than students expect.

    UsageUsually the canon; for one writer, the Shakespeare canon. Not to be confused with cannon, the gun.

    Note

    With the definite article, the canon sounds singular and settled, the shelf an educated reader is expected to know; a set like Great Books of the Western World sells it by the volume. Each field keeps its own, as in William Styron's "durable canon of American short fiction." Said of one writer, as in the Shakespeare canon, it asks a different question: not what deserves to be read but who wrote what.

    The Protestant canon of the Old Testament leaves out several books that Catholic Bibles include.

    Scholars still debate when the Hebrew canon of scripture was finally closed.

    Note

    Greek kanṓn was a measuring rod, so the canon of scripture is the set of books that measured up. Churches have drawn that line differently, which is why Catholic and Protestant Old Testaments differ in length. Books left outside are called noncanonical or apocryphal, and the literary sense of a body of accepted classics borrows its air of authority from this one.

Origins

Meanings 1–2, 4–7, 11–16

Ancient Greek κανών (kanṓn, "measuring rod, standard") is akin to κάννα (kánna, "reed"), from a Semitic source (compare Hebrew קָנֶה (qane) and Arabic قَنَاة (qanāh), both meaning "reed"). Latin took the Greek word as canōn, which passed into both Old French and Old English as canon and then into Middle English as canoun. It is a doublet of qanun. Compare also cane, cannon, canyon, and canal.
