Etymology: Originally < Middle French habonde abundant (15th cent.) < classical Latin abundus having plenty of water (2nd cent. a.d.), either < abundē abundantly ( < abundāre abound v.¹ + -ē , suffix forming adverbs) or directly < abundāre abound v.¹; in later use probably independently < abound v.¹ Compare earlier abundant adj.

Etymology: < Anglo-Norman abunder, abounder, habonder, habounder, Anglo-Norman and Old French, Middle French abonder, Anglo-Norman and Middle French habunder (French abonder ) (with de or en ) to have (something) in a large quantity (first half of the 12th cent.), to exist in a large quantity (late 12th cent.) < classical Latin abundāre to overflow, to emanate, issue, or spring forth, to flow copiously, to be full (of a liquid), to be plentifully supplied, to be rich in, to have plenty, to have an excess, to be plentiful or numerous, to be superfluous < ab- ab- prefix + undāre to flow in waves (see undation n.).Compare Old Occitan abondar , aondar (a1170), Catalan abundar (13th cent.), Spanish abundar (1325), Portuguese abundar (1415; 13th cent. as †avondar ), Italian abbondare (a1292; a1272 as †abondare ; a1306 as †abundare ). In to abound in one's own (or another's) sense at sense 4 after post-classical Latin abundare in suo sensu (Vulgate); compare Middle French, French abonder en son sens (c1190 in Old French). Spellings with h- in post-classical Latin, French, and English probably result partly from folk-etymological association with classical Latin habēre to have; compare abundance n., abundant adj. The early Scots past tense variant aboundanit may be a transmission error arising by confusion with the present participle aboundand.

Etymology: Probably < a- prefix¹ + bound v.¹
