Spoken English is full of pitfalls, but the transition from spoken to written English is particularly treacherous.

We have a venerable word, malapropism, for the substitution of an incorrect word for the proper one, which derives from Mrs. Malaprop in Richard Brinsley Sheridan’s The Rivals (1775). Malaprop, from the French mal a propos, roughly, badly to the purpose, inappropriate. Audiences have found her errors — "like an allegory on the banks of the Nile" — delicious for nearly two and a half centuries.

A cognate word is mondegreen, coined, according to Garner’s Modern American Usage, by Sylvia Wright in 1954 to label misheard lyrics, titles, catchphrases, slogans and the like. It derives from a child’s misunderstanding of a ballad lyric, "They hae slain the Earl o’ Moray and laid him on the green," as "They hae slain the Earl o’ Moray and Lady Mondegreen."

Mondegreens are numerous and widespread, a typical example being a child’s hearing the Christian hymn as "Gladly the cross-eyed bear." The title of this posting, a mishearing of the proverbial "dog-eat-dog world." comes from an essay by a Syracuse University student in a freshman English paper thirty years ago.

The tradition was upheld by the Sun reporter who filed a story with a reference to a "toe-headed boy." (Tow, or pale yellow flax or straw, has admittedly become a relatively uncommon word.) Another writer at the paper reported confidently that a candidate was a "shoe-in." (The idiomatic term is shoo-in.) And still another heard Putty Hill Avenue as Puddy Hill Avenue and wrote it accordingly.

The speakers and writers of English are so relentlessly creative that linguist Geoffrey Pullum coined yet another word, eggcorn, to describe an erroneous usage, after a writer who transformed the word acorn. An eggcorn is a homophone that suggests meaning and originality. Chris Waigl maintains a Web site, The Eggcorn Database,

, that contains more than 500 examples.

John Kenneth Galbraith once remarked, "If all else fails, immortality can always be assured by spectacular error." So if you must sin against standard usage, you should, like Mrs. Malaprop, sin boldly.
