From Old Norse yðvarr, from Proto-Germanic *izweraz, possessive of *jūz (“you (all)”) (see I). Cognate of Norwegian Bokmål deres, Swedish er, English your and German euer.
In most Germanic languages, it is an inflected adjective, but in modern Danish (and Norwegian), it is uninflected. In archaizing poetry, one may meet the possessive jer (jert, jere), which is probably reintroduced analogically to vor (“our”).
