bou m (plural boi)[1]

Etymology

It is inherited from Vulgar Latin *bovus (“ox”), a popular Latin form made on the oblique stem of bōs (accusative bovem).[2][3][4][5] DELR points to the form Late Latin bobus in the Mulomedicina Chironis as evidence for it.[3] Wiktionary takes the word from the accusative itself, possibly through the popular form.[1] The Latin word goes back to Proto-Indo-European *gʷṓws (“cattle”).[1]

The word survives in all four branches: Aromanian bou, Megleno-Romanian bou and Istro-Romanian bowu.[2][6][7][8][9] It is pan-Romance: Italian bove, French bœuf, Spanish buey, Portuguese boi, Catalan bou.[2][3]

Earliest recorded meaning

The first record is a personal name of 1235.[3][10] As a common noun it appears in the Psaltirea Hurmuzaki of the early 16th century, where boii “the oxen” are among the beasts given into man's hand (Psalm 8:7).[11][3] MDA2 dates its first record to Coresi's psalter of 1577.[4]

Semantic evolution

The literal sense, the castrated bull kept for draught and meat, has been the main one throughout.[5][12] Because the ox stood for slow, heavy work, many idioms grew up around it: a merge cu boii “to go very slowly”, a munci ca un bou “to work like a horse”, and a-și băga boii în jug cu cineva “to join forces with someone”.[10][4] A nu-i fi toți boii acasă “not to be in good spirits” is used of mental unease as well.[10]

The word became an insult for a stupid man, a sense Aromanian shares.[2][5][6] Compounds name other animals: bou-de-baltă for a toad, the bittern and a water beetle, boul-lui-Dumnezeu for the stag beetle or the ladybird, and bou-de-mare for a sea fish.[5] The family grew from the 16th century on: boulean and bouleț “young ox” in 1588, and bouar “oxherd” in 1612, which DELR derives from Latin boārius.[3]
