Etymology

The verb meaning to form grain is inherited from Middle English kirnen, also kerne and curne,[2][3][4] apparently inherited from Old English *cyrnan, a verb not recorded[3][4][5] and formed from corn, the source of corn.[4][5][6] The OED compares German körnen and Norwegian kyrna, and notes that an Old English verb seems to be implied by the obscure gloss gecyrnode.[3] The MED instead suggests it may come from kirnelen (“to develop seed”), from the noun that became kernel, and Dictionary.com calls the two verbs akin.[2][7] The noun, a grain, appears only in the 16th century; the OED relates it to the verb and to that noun, and compares Middle Dutch kerne, Dutch kern, Old High German cherno, Middle High German kerne, German Kern and Old Norse kjarni (“kernel, pip”), though it may continue an unrecorded Old English noun like Norwegian kyrne (“grain”).[3][6] Its meteorological sense, a condensation nucleus, was taken from German Kernzähler (“nucleus counter”), a term of 1913.[3][6]

Earliest recorded meaning

Of corn, to form the hard grains in the ear: 1297, in Robert of Gloucester's Chronicle,[3] whose line on green corn that should curne in summer the MED also quotes.[2]

Semantic evolution

From the 16th century the verb was also used of making salt into grains (1589–1726), of salting meat (1613) and of salt or sugar crystallizing (1657), senses that survived only in dialect.[3][6] The noun meant a kernel of a nut in 1570 and a grain of wheat or sand from 1753;[3][6] the 1989 edition of the OED dates its meteorological sense to 1941,[8] the current OED to 1951.[3] Wright's dialect dictionary records kern for a grain of corn and for the verb to form corn, to ripen or set (of beans or apples), in Scotland, Ireland, Northumberland and Yorkshire and in many southern counties from Gloucestershire and Kent to Cornwall.[9] Merriam-Webster labels both the verb and the noun dialectal English.[4]

kern2 Irish foot soldier

Confidence

Borrowing
First attested

Borrowed from
Middle Irish ceithern via Middle English
Ultimate origin
Old Irish ceithern

Etymology

The soldier is inherited from Middle English kerne, also kaerne,[2][10][4] borrowed from Middle Irish ceithern (“a troop of foot soldiers”),[2][10][4] from Old Irish ceithern (“band of foot soldiers”).[6][11][12] The MED notes that the spellings suggest the Irish word was already pronounced something like “kehern” or “ke'ern”.[2] The Shorter Oxford and Weekley give the modern Irish form ceithearn, and Weekley notes that it first meant a band of soldiers.[6][13] Merriam-Webster derives the Irish noun from cath (“battle”), akin to Gaulish catu- (“battle”) and Welsh cad,[4][5] and to Proto-Germanic *haþu- (“battle”), the source of Old English heaðo-, Old High German hadu- and Old Norse hǫð.[4][14] The same Irish word is the source of cateran, which is recorded earlier in English.[6][7][15]

Earliest recorded meaning

A light-armed Irish foot soldier: 1351 in the 1989 edition of the OED.[8] The MED finds the word earlier in the Latin and French of the Statutes of Ireland, as kaernias in 1297 and Keernes in 1316, and in English in the Rolls of Parliament of 1423.[2] Merriam-Webster dates the sense to the 15th century,[4] Hoad and Weekley to the 14th.[12][13]

Semantic evolution

Kerns were the poorer class of the "wild Irish", from whom such soldiers were drawn,[8] and the word was also used collectively for a troop of them (1422, now obsolete).[8][2] By transfer it came to mean a rustic or boor, and contemptuously a vagabond or rascal: the 1989 edition of the OED dates this to 1553,[8] the Shorter Oxford to the late 15th century.[6] Johnson (1755) called it an Irish word for an Irish foot soldier or an Irish boor, quoting Spenser.[16] The word was also used of the Scottish Highlands: Merriam-Webster defines the soldier as one of medieval Ireland or Scotland,[4] and Wright's dialect dictionary has Scottish and Northumbrian quotations, from Scott's Rob Roy (1817) on, for a foot soldier or freebooter, with the Scottish sense of a vagabond or sturdy beggar.[9]

Timeline

  • 1297 – the plural kaernias in the Latin of the Statutes of Ireland.[2]
  • 1351 – a light-armed Irish foot soldier.[8]
  • 1422 – collectively, a troop of Irish foot soldiers (obsolete).[8][2]
  • 1553 – a rustic or boor; a vagabond or rascal.[8]

Meanings

Noun

  1. (historical) A lightly armed foot soldier of medieval Ireland or the Scottish Highlands.[4][6][17]
  2. (archaic) A rustic or boor.[4][6][8]
  3. (obsolete) A troop of such soldiers.[8][17]

kern3 projecting part of a letter

Confidence
Probable
Formation
Borrowing
First attested
1683 Moxon's Mechanick Exercises
Borrowed from
French carne
Ultimate origin
Latin cardō

Etymology

The part of a letter is probably borrowed from French carne (“corner, projecting angle, nib of a quill pen”),[3][4][10][6][12][18] a northern form, from Picardy and Normandy,[4][6][3] of Old French charne (“hinge, pivot”),[19][6][12] from Latin cardō (“hinge”) (stem cardin-),[3][4][6][19] the source of cardinal.[4] The OED and Hoad take the English form as standing for an unrecorded “carn”.[3][12] Etymonline reports that the Century Dictionary instead took it as identical with kern in the sense "grain", the first word above.[19] The verb is formed from the noun.[3][6]

Earliest recorded meaning

A part of a metal type projecting beyond its body or shank, such as the curled head of f and the tail of j: 1683, in Joseph Moxon's Mechanick Exercises, where the verb, to furnish a type with a kern, also first appears.[3][4][19]

Semantic evolution

The noun first belonged to hand-set metal type, where the kern rested on the neighbouring letter.[3][17] The verb meant to cast a type with a kern;[3][6] with the later meaning of kern as any part of a printed character that overlaps its neighbour, the verb came to mean making selected characters overlap, and now also adjusting the spacing between characters.[6][17] Collins defines kerning as the adjustment of the space between characters.[20]

Timeline

  • 1683 – the projecting part of a metal type; also the verb, to furnish a type with a kern.[3][4]

Meanings

Noun

  1. The part of a letter in typography that projects beyond the body of the type or over the neighbouring character, such as the tail of a Q.[20][4][6]

Verb

  1. To give a letter or typeface a kern.[20][3][17]
  2. To adjust the space between pairs of characters: The designer kerned the headline by hand.[6][17]
