köken: Inherited from Middle French croc, from Old French croc, croke (“curved instrument, hook”), from Frankish *krōk (“hook”) or from Old Norse krókr (“hook, bend, bight”), both from Proto-Germanic *krōkaz (“hook”), from Proto-Indo-European *greg- (“tracery, basket, twist”). Cognate with Middle Dutch croec, crōc (“curl”), Middle English crōc (“crook, hook”). More at crook, crooked.

köken: Etymology tree Proto-Indo-European *ǵembʰ- Proto-Indo-European *-os Proto-Indo-European *ǵómbʰos Proto-Balto-Slavic *źámbas Proto-Slavic *zǫbъ Old Church Slavonic зѫбъ (zǫbŭ) Bulgarian зъб Inherited from Old Church Slavonic зѫбъ (zǫbŭ), from Proto-Slavic *zǫbъ.
köken: Uncertain. Viredaz tentatively derives the word from a Proto-Celtic *skixtro-, from *skrixtro-, from Proto-Indo-European *skr̥̮p-tro-, from the zero-grade of *(s)kerp- (“to cut, harvest”) (with s-mobile) + *-trom (“instrumental suffix”). However, *(s)kerp- is otherwise absent in Celtic, in addition to all other derivatives lacking the s-mobile.
