(obsolete terminology) The 'to'-prefixed infinitive in English or other Germanic languages, so named because the infinitive was regarded as a verbal noun and the 'to'-prefixed form of it was seen as the dative form of the verbal noun; the full infinitive.

The word is cognate with Catalan supí, Italian supino, Old French sovin, Middle French souvin, Anglo-Norman supin, Old Occitan sobin, sopin, Portuguese supino, Spanish supino. Partly displaced , whence Modern English upward.
The noun is from Late Middle English supin ("supine of a Latin verb") or Middle French supin ("(grammar) supine"), from Latin supīnum, (ellipsis of supīnum verbum), from supīnus; further etymology above.
