Inherited from
Middle English nagge

Etymology

The horse is inherited from Middle English nagge (“small riding horse, pony”),[2][3][4][5] of unknown or uncertain origin.[2][6][7][8][9] Several dictionaries compare Dutch negge,[4][5][3][2] which the OED finds in Junius's “Nomenclator” of 1567, with nagge as its English equivalent;[6] Etymonline notes that the Dutch forms are later than the English word.[2] The OED, following the Middle English Dictionary, suggests that it may come from neigh, but finds the sound change difficult;[6] Merriam-Webster too thinks it probably related to Old English hnǣgan (“to neigh”),[4] and Barnhart to Middle Dutch nighen (“to neigh”).[3] Johnson took it from Dutch.[10]

Earliest recorded meaning

A small riding horse or pony: 1336–7, in a medieval household account.[6] Etymonline dates it to about 1400,[2] and Barnhart to probably before 1400.[3]

Semantic evolution

The word first meant a small saddle horse or pony,[6][4] and colloquially any horse; it now usually means an old or feeble one.[6] Barnhart thinks this sense developed from the use of nag as a term of abuse, which he dates to 1598,[3] and Etymonline calls the abusive sense for a worthless person, often a woman, a transferred one from the 1590s.[2] In Elizabethan and Jacobean slang a nag was also the penis (1598–1709) and a prostitute (1608–30),[6][11] and Johnson (1755) defined it as a paramour, in contempt.[10] Merriam-Webster records a slang sense "racehorse".[4] In Cumberland dialect nag-back meant horseback, and in Cornwall nag-ridden meant troubled by nightmares.[12]

Borrowed from
Old Norse nagga
Ultimate origin
Old Norse nagga

Etymology

The verb is probably a regional reflex of a word borrowed from Old Norse nagga (“to rub, grumble”),[6][3][4][13][5] an intensive formation from the same Scandinavian base as gnaga (“to gnaw”), the source of gnaw.[6][2][5] The OED and Barnhart compare Icelandic nagga (“to complain, grumble”),[6][3] Faroese nagga (“to rub”), Norwegian Nynorsk nagga (“to gnaw, irritate, grumble”), regional Swedish nagga and Danish nagge;[6][3][4] Hoad and the Oxford Dictionary of English also allow a Low German origin, comparing Low German naggen (“to irritate, provoke”),[8][9][7] and the OED compares Middle Dutch naggen (“to irritate, provoke”) as a parallel formation.[6] In Orkney and Shetland the word probably comes from Norn.[6] The Old Norse verb and Old English gnagan (“to gnaw”) go back to Proto-Germanic *gnaganą (“to gnaw”).[2][14][15]

Earliest recorded meaning

To gnaw or nibble: before 1728, in White Kennett's manuscript collection of provincial words,[6] 1825 in Halliwell according to Etymonline.[2] The verb was originally regional, chiefly British.[6][9]

Semantic evolution

The literal "gnaw" is still the verb's first sense in the English Dialect Dictionary, which records nag "to bite, to snap" in Scotland and also "to nick, to notch".[12] The figurative "gnaw at a person" gave the main modern sense, to find fault or scold persistently, from 1801 in the OED,[6] about 1828 in Merriam-Webster, Barnhart and Etymonline.[4][3][2] From 1802 it was used with at before the person; transitive use followed in 1849.[6] Since 1831 it has also been used of a dull, persistent ache.[6][7] The noun, a person who nags, is from 1850,[6] and an act of nagging from 1866.[6][4]
