To elongate something is to make it longer than it was; if a thing elongates, it becomes longer itself. The idea is physical length, not time: a shadow elongates in the evening; a test may elongate a metal bar by a tiny amount. It is a more formal, slightly scientific cousin of stretch and . also use elongate as a describing word for a long, thin shape (an elongate leaf), though the everyday describing form is elongated. You would not usually elongate a meeting — that is prolong or extend. The word is at home in science, art, and careful description, not in chat.
拉長；使變長
組成From Latin ēlongātus, “stretched out,” from ē- (out, away) + longus (long). English borrowed that form and uses it as a verb, and in science sometimes as a describing word.
