worms

From Old High German Wormazia, Warmazia, etc., from Latin Vormatia, from a Gaulish name attested in Latin as Borbetomagus and Bormitomagus with influence from Latin -ātus (suffix forming adjectives) and suffix forming place names, of uncertain origin but usually conjectured to refer to the Celtic god Borvo or a river, spring, or other waters named for him + Proto-Celtic *magos (“field, plain”).
