cairn

Etymology

It is inherited from Middle English carne, a Scots form,^[2][3][4] borrowed from Scottish Gaelic càrn (“heap of stones”),^{[5][2][3][6][1]} which is from Old Irish carn.^[2][1] The OED explains cairn as the modern Scottish form of earlier carn, with the same vowel change as bairn.^[5][7] It is found in Lowland Scots in the early 16th century and passed into English as a term of archaeology and, later, for the piles of stones raised by surveyors.^[5] The word occurs in all the Celtic languages,^[5] for example Welsh carn (“heap”),^[5][8][9] and Wiktionary reconstructs Proto-Celtic *karnos.^[1] Since Welsh carn also means hoof and the handle of a knife, which points to an earlier sense "horn", the OED and Barnhart consider identifying it with Gaulish karnon (“horn”), so that a cairn would first have been the "horn" on a mountain top; the OED calls this possible but not certain.^[5][8] Etymonline likewise links it, perhaps, to Proto-Indo-European *ker- (“horn; highest part of the body”), the source of horn,^[10] and Webster's Third and Merriam-Webster compare hard.^[4][11]

Earliest recorded meaning

A pile of stones raised as a memorial or over a grave: in William Stewart's translation of Boece's chronicle of Scotland (1535, in a manuscript of before 1600).^[5][8][10] Merriam-Webster and the Shorter Oxford date the word to the 15th century,^[3][11][12] and Hoad to the 15th century, with an earlier form carn.^[7]

Semantic evolution

The first cairns in the record are memorials and grave-mounds,^[5] and the word spread in English as a term for prehistoric stone mounds.^[5] It is used of a mere heap of stones from 1699,^[5] and of a cairn as a landmark or boundary mark, on a mountain top or to show travellers where a store was left, from 1770, in John Wesley.^[5][13] The direct English form of the Celtic word would be carn, which the OED notes is common on maps of Wales.^[5] The cairn terrier, recorded from 1910, is said to be named from being used to hunt among cairns.^[5][14][15] The verb, to mark with a cairn, is recorded from 1937.^[5][13]
