köken: From べた (beta) + 踏(ふ)み (fumi, “連(れん)用(よう)形(けい) (ren'yōkei, “stem or continuative form”) of the verb 踏(ふ)む (fumu).”). The fumi changes to bumi as an instance of rendaku (連濁).
köken: From a (“to, at”) + lume (“fire”) + de (“of”) + biqueira (“toecap”): because the metal toecaps of the boots produced sparks when walking at top speed over a paved road.
coma se acabasen de recibir unha orde, dirixíronse a lume de biqueira a un dos barracóns
