Etaoin shrdlu (/ /, / /) is a nonsense phrase that sometimes appeared in print in the days of "hot type" publishing because of a custom of type-casting machine operators. It appeared often enough to become part of newspaper lore, and "etaoin shrdlu" is listed in the Oxford English Dictionary and in the Random House Webster's Unabridged Dictionary.
It is the approximate order of frequency of the 12 most commonly used letters in the English language.
The letters on type-casting machine keyboards (such as Linotype and Intertype) were arranged by descending letter frequency to speed up the mechanical operation of the machine, so lower-case
s-h-r-d-l-u were the first two columns on the left side of the keyboard.
Each key would cause a brass "mat" (an individual letter mold) from the corresponding slot in a font magazine to drop and be added to a line mold. After a line had been cast, the constituent mats of its mold were returned to the font magazine. The mats moved along a rail, and dropped into matching keyed slots. Because "e" was the most frequently used letter, it had the first slot, giving it the shortest round trip through the machine.
If a mistake was made, it was normally faster to finish the faulty line mold and discard the resulting cast line of type, than to dismantle a partially assembled line mold and manually return its constituent mats to the magazine. Since this was simpler if the line were padded out to full width, operators would finish a faulty line by running a finger down the first columns of the keyboard, making a sequence which was both convenient for operators and a pattern easily spotted by proofreaders.
However occasionally such a line would be overlooked, and make its way into print.
A documentary about the last issue of The New York Times to be composed using the hot-metal printing process (2 July 1978) was titled Farewell, Etaoin Shrdlu.
