hash

hash¹ chopped food; mess

Etymology

The dish of chopped food is a noun formed from the verb meaning to chop,^[2][3][4][5] which is borrowed from Middle French hacher (“to cut into small pieces, chop up”),^[2][3][5][4] from Old French hache (“axe”), the source of hatchet.^[3][5][4] The Anglo-Norman verb is recorded from the early 13th century, already meaning to chop up or mince.^[6] The French noun hache is of Germanic origin,^[7][8] perhaps from Frankish *happja,^[3][9] and is related to Old High German happa (“sickle, pruning knife”).^[8][3] Etymonline tentatively connects the Germanic word with Proto-Indo-European *kop- (“to beat, strike”), the root of Greek words for striking and cutting,^[3] and Merriam-Webster compares the Greek verb for to smite;^[8] Klein derives it from an Indo-European base meaning to cut.^[9] The English noun replaced the earlier hachy,^[4][2] and its first record (1653) follows French hachis;^[2][10] Barnhart dates the earlier form, as hache, to about 1330.^[11]

Earliest recorded meaning

To cut, slash or mangle: 1591–2, in the Scots poem Rob Stene's Dream.^[2] Merriam-Webster dates the verb to 1590, in the sense of chopping to pieces,^[8] and Etymonline to the 1650s.^[3]

Semantic evolution

The cookery sense, to cut meat or food finely, is recorded from 1615,^[2] and the noun, a dish of chopped and usually previously cooked meat, from 1653, in a translation of La Varenne's French Cook;^[2] Pepys used it in 1662–3.^[2][11] The same year the noun was used of old material served up in a new form, which became rehash.^[2][4] From 1660 a hash was a jumble or mess, especially in to make a hash of;^[2][4] Etymonline dates "a mix, a mess" to 1735.^[3] Weekley compares to settle one's hash, recorded from 1795, with to cook one's goose.^[2][10] In American English hash became cheap food in general (1865),^[2] and to hash meant to work as a waiter in a café (1899–1900).^[12] In Scottish use a hash was also a clumsy or foolish person (1655),^[2][4] and the English Dialect Dictionary records a mess or muddle in Scotland, Ireland and the north of England, and in Northumberland a dish of minced sheep's lights.^[13] Hash browns (1926) are short for hashed browned potatoes (1886).^[3] Radio engineers called random noise in a signal hash from 1923,^[2] and programmers used the verb from 1966 for turning data into a fixed-length value by a hash function, a sense Etymonline dates to 1979.^[2][3]

hash³ the sign #

Etymology

The sign # is probably a shortening of hash mark,^[2] which the OED takes as hatch, to mark with fine parallel lines, and mark, altered by association with the related verb meaning to chop.^[2] The American Heritage Dictionary and the Concise Oxford likewise derive it from hatch in this sense, altered by folk etymology under the influence of the cookery word,^[7][15][17] and the Oxford Dictionary of Word Origins traces it to the same use of hatch.^[16] Etymonline mentions the story that military service stripes counted years of free food (hash) from the army, but thinks a link with hatch possible.^[3]

Earliest recorded meaning

The symbol #: 1967, in an annual report of the South African Council for Scientific and Industrial Research.^[2] The fuller hash mark is recorded in this sense from 1961.^[2] Word Origins dates the sign's name to the 1960s,^[16] while the Concise Oxford and the Oxford Dictionary of English give the 1980s.^[15][17]

Semantic evolution

Hash mark first meant a service stripe on an American military sleeve (1907), then any short tally line and the yard markers of an American football field (1948), before it was applied to the symbol.^[2][3][8] The short form also names the key bearing the sign on a keyboard or telephone keypad,^[2] and gave hashtag, first recorded in 2007.^[16]
