1. In Latin, a noun derived from a verb and having all case forms except the nominative.
2. In other languages, a verbal noun analogous to the Latin gerund, such as the English form ending in -ing when used as a noun, as in singing in We admired the choir's singing.

[Late Latin gerundium, from alteration (modeled on participium, participle) of Latin gerundum, variant of gerendum, neuter gerundive of gerere, to carry on.]
