ample (adj.)

mid-15c., "great, abundant," especially "sufficient for any purpose," from Old French ample "large, wide, vast, great" (12c.), from Latin amplus "large, spacious; abundant, numerous; magnificent, distinguished," which is related to ampla "handle, grip; opportunity," from Proto-Italic *amlo- "seizable," from a PIE root meaning "to grab" that also is postulated as the source of amare "to love" (see Amy).
