The Elements of Style is a prescriptive American English writing style guide in numerous editions. The original was composed 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 forty-nine "words and expressions commonly misused," and a list of fifty-seven "words often misspelled." It was much enlarged and revised by E.B. White for publication by Macmillan in 1959. That was the first edition of so-called Strunk & White, which Time magazine named in 2011 one of the 100 best and most influential books written in English since 1923.
