Latin

語源

The latter element is the common suffix -men; the former is from Proto-Indo-European *gʷétu (“pitch”) via an Italic language in which *gʷ became b, e.g. Oscan or Umbrian.^[1] (The traditional derivation from Celtic is implausible as the related Celtic words—Old Irish beithe, Welsh bedw, かつ the Gaulish source of Spanish biezo—mean only ‘birch’, not ‘pitch’.)

Cognate with Scottish Gaelic bìth (“resin, gum”), English cud, Sanskrit जतु (jatu, “lac, gum”). Influenced by ferrūmen (“cement, glue”).
