Supine (2)

Su″pine (sū″pīn), n. [L. supinum (sc. verbum), from supinus bent or thrown backward, perhaps so called because, although furnished with substantive case endings, it rests or falls back, as it were, on the verb: cf. F. supin.] (Lat. Gram.) A verbal noun; or (according to C.F.Becker), a case of the infinitive mood ending in -um and -u, that in -um being sometimes called the former supine, and that in -u the latter supine.
