Forms

uncus m (genitive uncī); second declension[1]

Etymology

It is inherited from Proto-Italic *onko-, inherited from Proto-Indo-European *h₂onḱ-o- (“hook”).[2][1] Cognate with Sanskrit अङ्क (aṅká-, “hook, bend”), Ancient Greek ὄγκος (ónkos, “barb of an arrow”) and Old English anga (“hook”), and ancus “crook-armed” and angulus “corner” come from a related root.[2][3][1]

Earliest recorded meaning

De Vaan and Köbler date it from Cato, who lists iron hooks among farm equipment.[2][4][5] Köbler dates Cato 234–149 BC.[4]

Semantic evolution

The noun was a hook used for any purpose, and especially the hook with which the bodies of executed criminals were dragged to the Tiber, as Cicero speaks of the scourge, the hook and the cross.[3] In building it was a clamp fixing stone facing to a core, and Horace gives Necessity a stern clamp.[3][6] The adjective uncus meant hooked, curved, as Lucretius' and Virgil's curved ploughshare.[3][6]

Döderlein says uncus supposes a strong curve, a hook, while curvus is any crookedness.[7] In medieval Poland and Bohemia uncus, from a Slavic word, was a measure of land.[8][4] Uncīnus “hook” gave the adjective English uncinate “hooked”.[1]
