Forms

âcre (plural âcres)[1]

Etymology

It is borrowed from Latin ācer (“sharp, pointed, pungent”), whose forms passed into the second declension in Vulgar Latin.[2][3][1][4] It is the learned doublet of aigre, the inherited outcome of the same Latin word.[2][3][1][5] Bloch and Wartburg say it was borrowed for a sensation stronger than sourness.[6]

Bloch–Wartburg and the GLLF date it to the 14th century, but the Grand Robert and the TLFi show that this rests on a misreading: the spelling ⟨aucres⟩ quoted by Godefroy from a Girart de Roussillon text of 1334 is a bad transcription of ⟨ancrés⟩, a form of Old French engrès.[6][5][7][2] Littré already noted that the word is not found in Old French and called it a new form modelled on Latin beside the old inherited form.[8] The Rey dictionary thinks it was probably in use somewhat before 1606, and at first only in medicine.[3][2]

Earliest recorded meaning

Nicot's dictionary of 1606 is the first to record it, for a sharp taste or smell such as that of onions.[2][7][4]

Semantic evolution

At first it seems to have been mostly a physicians' word: Richelet gives urine âcre in 1680, and Furetière in 1690 says that physicians call âcre any taste that leaves a burning heat on the tongue.[2][3] It was used of taste, smell and also hearing.[3]

Cotgrave in 1611 already applies it to a person in the sense “eager, sharp, vehement”,[2] and the figurative use for what is irritating, aggressive or bitter remained mostly literary.[3][4][9] The noun âcreté dates from before 1590, and the rare adverb âcrement from 1840.[3]
