Where it comes from
Unadapted borrowing from Middle French resipiscence (“act of recovering one’s senses or coming back to a more acceptable view; repentance”) (modern French résipiscence), or from its etymon Late Latin resipīscentia (“regaining of a clear state of mind, repentance”), from Latin resipīscēns + -ia (suffix forming feminine abstract nouns). Resipīscēns is the present participle of resipīscō (“to recover one’s senses; to revive”), from re- (prefix meaning ‘again’) + sapiō (“to have flavour or taste; (figurative) to have good taste or discernment; to be sensible or wise”) (ultimately from Proto-Indo-European *seh₁p-, *sep- (“to taste; to try out”)) + -īscō (a variant of -ēscō (suffix forming adjectives with the sense ‘becoming [something]’)).
