Word Origin and History for supine



c.1500, from Latin supinus "turned or thrown backwards, inactive, indolent," related to sub "under" (see sub-). The grammatical use for "Latin verbal noun formed from the past participle stem" 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.
