Etymology
It is inherited from Latin cōleus (“testicle”).[2][3][4][5][6] Wiktionary sets a Vulgar Latin neuter *coleum between the two, made neuter because testicles come in pairs, hence the Romanian neuter.[1] It survives in two other branches: Aromanian col'u, plural ⟨coal'e⟩, and Istro-Romanian col'e.[3][7] The Romance cognates are Italian coglia, Occitan colh, Old French coil and its modern form French couille, and Spanish cojón.[3][8] Ciorănescu compares Albanian kulje (“hernia”).[3]
Earliest recorded meaning
DELR's first record is from 1592–1604.[2] Tiktin cites a document of 1621 and the Bible of 1688, whose list of bodily defects in Leviticus includes „să fie cu un coiu” “that he has one testicle”.[5][9]
Semantic evolution
Besides the anatomical sense the word names the sliding weight of a steelyard, and with the plural coiuri a rubber ball.[2][3] Used familiarly as a masculine noun or adjective it means a bold, energetic man, and cu coaie is “uncastrated”.[6] Its derivatives are old: coișor appears in a personal name in 1621, coian “a man with large testicles” c. 1650, and coios, also “suffering from hernia”, in 1825.[2]
