See also: fisher groundhog (def. 1) wejack woodshock
- This word appears to have been derived by folk etymology from earlier woodshock, q.v., itself a folk etymology meaning fisher, q.v., from an Algonkian word of similar meaning, as Cree o(t)chāk, which also came into English as wejack, q.v. At some time in the eighteenth century the term woodshock appears to have been transferred from the fisher to the groundhog, in which sense the alteration woodchuck has become generalized.
