Forms

aïeul m (plural aïeuls or aïeux, feminine aïeule)[1] Old French aiuel (about 1050), aioel (early 13th century); feminine aiuele (about 1180).[2] Two plurals: aïeux, from the old oblique plural aiues, aieus, and aïeuls, remade on the singular in the 17th century.[2][3]

Etymology

It is inherited from Old French aiuel, inherited from Vulgar Latin *aviolus, feminine *aviola, a diminutive of Latin avus (“grandfather”), feminine avia.[2][4][5][1][6] Bloch and Wartburg call its sound development irregular, as often happens in kinship terms.[5] Rey notes that the Latin word was not first a kinship term but a familiar name for an elder of the group, and that it is of Indo-European origin; the Latin avunculus derived from it gave oncle.[2]

Cognate with Italian avolo, Old Occitan aviol and Spanish abuelo;[7] Littré also cites Berry aïol and Walloon aiouz.[7]

Earliest recorded meaning

It first meant “grandfather” (about 1050), and the feminine “grandmother” (about 1180).[2]

Semantic evolution

From the early 13th century the masculine also meant “ancestor”, often in the plural.[2] In the 18th century the two plurals were told apart: aïeux for the ancestors, aïeuls for the grandparents.[2] From the 16th century grand-père replaced it in the sense “grandfather”, and aïeul became a literary word.[5][8] In the sense “ancestor” it has extended and figurative uses (from 1821).[2] The familiar exclamation mes aïeux ! calls one's ancestors to witness something remarkable.[3]
