Question

supine a.仰卧的；懒散的 supine (adj.) c.1500, "lying on the back," from Latin supinus "bent backwards, thrown backwards, lying on the back," figuratively "inactive, indolent," from PIE *(s)up- (see sub-). The grammatical use for "Latin verbal noun formed from the past participle stem" (mid-15c.) is from Late Latin supinum verbum "supine verb," perhaps so called because, though furnished with a noun case ending, it "falls back" on the verb. Related: Supinely. 【记】super + 音：拍，晚饭后拍拍肚子懒散地躺床上→仰卧【相关】prone 俯卧
