ETAOIN SHRDLU

The sequence in The New York Times (October 30, 1903).

ETAOIN SHRDLU (English pronunciation: /ˈɛteiˌɔɪn ˈʃrədlu/[1]) is a nonsense phrase that sometimes appeared in print in the days of "hot type" publishing because of a custom of Linotype machine operators. It appeared frequently enough that it became part of the lore of newspapers. A documentary about the last issue of The New York Times to be composed in the hot-metal printing process (2 July 1978) was titled Farewell, Etaoin Shrdlu.[2]

It is the approximate order of frequency of the 12 most commonly used letters in the English language.

Linotype history

A linotype keyboard. It has the following alphabet arrangement twice, once for lower-case and once for upper-case letters, with extra keys for numbers and symbols: etaoin / shrdlu / cmfwyp / vbgkqj / xz

The letters on Linotype keyboards were arranged by letter frequency, so "etaoin shrdlu" were the first two vertical columns on the left side of the keyboard. Linotype operators who had made a typing error could not go back to delete it, and had to finish the line before they could eject the slug and re-key a new one. Since the line with the error would be discarded and hence its contents did not matter, the quickest way to finish the line was to run a finger down the keys — a "run down", as it was termed — creating this nonsense phrase.

If the slug with the error made it as far as the compositors, the distinctive set of letters served to quickly identify it for removal. Occasionally, however, the phrase would be overlooked and be printed erroneously. This happened often enough for ETAOIN SHRDLU to be listed in the Oxford English Dictionary and in the Random House Webster's Unabridged Dictionary.
