Forms
patruēlis m or f (genitive patruēlis); third declension[1] Ablative singular patruēle in Nepos, beside the usual patruēlī.[2][3][4]
Etymology
It is from Latin patruus (“father's brother”) + -ēlis.[2][1][4] De Vaan, following Leumann, suggests that it may be dissimilated from an older *patruīlis, “of a father's brother”.[5] The noun patruus belongs to pater (“father”) and goes back to Proto-Indo-European *ph₂tr-u- (“father's brother”).[5]
Related words for the father's brother are Sanskrit पितृव्य (pitr̥vya-) and Young Avestan tūiriia- (“father's brother”).[5]
Earliest recorded meaning
Köbler, de Vaan and the TLL record it first in Naevius,[6][5][4] who has fratri patrueli meo, “to my cousin”.[4] In Plautus' Poenulus two Carthaginians are said to have been fratres patrueles, first cousins.[2]
Semantic evolution
Its first use is the phrase frater patruēlis or soror patruēlis, a cousin through one's father's brother, as against cōnsobrīnus, a cousin through one's mother's sister.[3][2] Cicero calls Lucius Cicero his brother by kinship patruelis, by affection germanus.[3][4] Jurists place the fratres and sorores patrueles in the fourth degree of kinship.[4] Used alone as a noun it means a cousin, in Suetonius and Persius,[3] and Cicero once uses it of a father's sister's son.[3] Poets use it more loosely: Ovid has patruelis origo, and the patruelia dona are gifts that belonged to a cousin.[2][3]
In Medieval Latin it could mean the father's brother himself,[7][8] and writers in Britain also use it for a cousin or a nephew.[8]
