From Proto-Baltic; cf. Lithuanian opšrùs, Old Prussian wobsdus. The source may be Proto-Indo-European *op- (“to do, carry out”), from which Latvian regionalism āpēties (“work hard”) (cf. Sanskrit अपः (ápaḥ, “work, organizing”), Latin opus (“work, task”)). This name would be justified by the badger's well-made burrows. A parallel case is German Dachs (“badger”) from Proto-Indo-European *tek- (“weave, build”).
