词源

Etymology tree Akkadian napṭumbor.? Old Persian *naftahbor. Ancient Greek νάφθα (náphtha)bor. Latin naphthabor. English naphtha From Latin naphtha, from Ancient Greek νάφθα (náphtha, “naphtha”), from Old Persian *naftah, probably borrowed or assimilated from Akkadian 𒉌𒆳𒊏 (napṭu, “naphtha”) . The Greek mediation is reflected in the spelling – ‘ph’ and ‘th’ (from ‘φ’ and ‘θ’).
