The Elements of Style is an American English writing style guide in numerous editions. The original was written by William Strunk Jr. in 1918, and published by Harcourt in 1920, comprising eight "elementary rules of usage", ten "elementary principles of composition", "a few matters of form", a list of 49 "words and expressions commonly misused", and a list of 57 "words often misspelled". E. B. White greatly enlarged and revised the book for publication by Macmillan in 1959. That was the first edition of the so-called Strunk & White, which Time named in 2011 as one of the 100 best and most influential books written in English since 1923.

American poet Dorothy Parker said, regarding the book:

If you have any young friends who aspire to become writers, the second-greatest favor you can do them is to present them with copies of The Elements of Style. The first-greatest, of course, is to shoot them now, while they're happy.
