premolars の類義語・関連語
premolars の語源・成り立ち Etymology
ラテン語 prae(前)+ molaris(臼歯、mola「臼」から)の合成語。大臼歯(molar)の前に位置する歯なので「小臼歯」。関連語: molar(臼歯)、premature(早すぎる)。接頭辞 pre- が「前」を示す典型例。
Premolars comes from pre- meaning "before" and molar, from Latin molaris, based on mola, meaning "millstone" or "grinding stone." The name was given because these teeth stand in front of the molars. Related words include molar and premature, which also uses pre- for the idea of "before."
