Etymology

It is inherited from Middle English frok, also spelt frogge,[2][3] borrowed from Old French froc (“monk's habit; gown, mantle”),[4][5][6][7][8] with the Anglo-Norman spellings frock and frogge.[4] The Anglo-Norman word is recorded from about 1136, for a coat or tunic and for a monk's woollen habit with large open sleeves.[9] Most dictionaries take the French word, with French f in place of a Germanic h, from a Germanic word, probably Frankish *hroc,[4][6][8][10][11] from Proto-Germanic *hrukkaz;[1][11] its relatives are Old Frisian hrok, Old Saxon hrokk and Old High German hroc (“mantle, coat”),[4][6][3] and, in forms without the initial h, Old English rocc, Old Norse rokkr and German Rock (“coat”).[4][5][10][11] The OED leaves the source as an unattested Frankish or Old Dutch word, and suggests that the irregular variation between forms with and without the initial h points to a borrowing from a substrate language.[4] Kroonen notes that the French word was later taken into German as Frack, and he rejects the comparison with Old Irish rucht (“jacket, tunic”),[11] which Klein and Merriam-Webster Unabridged make.[10][3] Etymonline calls the French word of unknown origin and mentions a theory that traces it to Medieval Latin floccus, from floccus (“tuft of wool”),[5] as Skeat did.[12] The OED explains the Medieval Latin forms hroccus, recorded from the 9th century, and froccus as borrowings from Germanic, and the forms spelt with fl as reshaped after the classical Latin word.[4]

Earliest recorded meaning

A long outer garment with loose sleeves worn by monks: 1350, in the account rolls of Durham Abbey, which list ij frokkes.[4][2] Barnhart and Etymonline also date the word to 1350 or the mid-14th century.[6][5]

Semantic evolution

Ayto notes that the word first meant a long coat or tunic, a sense close to that of its Old High German relative, and that it survives in frock coat; because the frock once stood for the priest's office, a priest who was dismissed was unfrocked.[13] The Oxford Dictionary of English likewise sees the original sense, a priest's or monk's gown, preserved in defrock, recorded from the late 16th century.[14] From 1589 the word stood for the priestly life itself, as in to take the frock, to become a monk or priest.[4] About 1400 it was used of a long coat or tunic in general,[4] and since the 1530s it has been used of a garment worn by women and girls,[4][5][6][13] now chiefly British for a dress.[4][15] Workers' and peasants' loose overgarments were frocks from 1596, the smock frock,[4] and in Nottinghamshire and Sussex dialect a frock was still a labourer's smock or a miner's or mason's blouse in the 19th century.[16] Johnson (1755) defined it simply as a dress or a coat, quoting Hamlet and Milton.[17] Later senses are a coat of mail (1658), a man's informal coat (1719), a sailor's woollen jersey (1796) and the long-skirted frock coat,[4][3] which Etymonline records by 1819.[5] In 1919 H. Wilson's diary used frocks scornfully for the civilian, as opposed to military, leaders of the First World War.[4] Weekley compared the wide range of senses with that of gown.[18]
