croquet: [19] Old Norse krókr ‘hook’ (source of English crook) was borrowed into Old French as croc. This formed the basis of a diminutive, crochet, literally ‘little hook’, which has passed into English in various guises over the centuries. First to arrive was crotchet [14], applied to musical notes from their hooked shape. Crocket ‘curling ornamental device’ followed in the 17th century, via the Old Northern French variant croquet. Crochet itself, in the ‘knitting’ sense, arrived in the 19th century.

And in the mid 19th century croquet, apparently a dialectal variant of French crochet, was applied to the lawn game with balls and mallets newly introduced from Ireland to Britain. Old French croc was also the ancestor of encroach.
