Pronunciation

  • IPA: /ɛ̃.be.sil/[1]

Forms

imbécile (plural imbéciles)[1] The spelling imbecille (1508), usual in the 17th century, is still found early in the 19th; the Académie spelled it so from 1694 to 1762.[2][3]

Etymology

It is borrowed from Latin imbēcillus (“weak in body or mind; without character”) (1495–1496),[3][2][4][5] explained as literally “without a staff, without support”, from in- (“not”) and bacillum (“little staff”), a diminutive of baculum (“staff, stick”);[2][4][6] Rey relates it to an Indo-European root Proto-Indo-European *bak- (“staff”).[2] Littré thought the Latin word of doubtful origin, since the vowel lengths of the supposed parts do not agree.[7]

Earliest recorded meaning

It is first found in 1496 in the Latin sense “physically weak”;[3][2] Robert Garnier calls women le sexe imbecile (1580).[3][2]

Semantic evolution

Imbecille de sens “weak in mind” (1509) prepared the sense “lacking intelligence”: imbecille jugement (1548), and of persons in Montaigne (1595).[3][2] The Latin sense “lacking moral strength” is in Calvin (1541) and was common in classical French;[2][8] Pascal still calls man an imbécile ver de terre, “feeble earthworm”.[2][8] Bloch and Wartburg note that the modern sense won out in the 17th century.[9] In medicine it meant “feeble-minded” from 1671 (Pomey).[3][2]

As an insult it is largely emptied of meaning (espèce d'imbécile), like idiot and crétin;[2][6] imbécile heureux is a fool pleased with himself.[2] imbécillité is older, from the 14th century (Bersuire).[9] The adverb imbécilement (1542) first meant “weakly”; its modern sense is in Saint-Simon.[2]
