In large quantities; plentifully or copiously. To a very great degree; extremely or exceedingly.
From Latin abundanter, from abundare meaning 'to overflow,' composed of ab- 'away' and undare 'to rise in waves' (from unda 'wave'). The word literally means 'flowing away in waves,' entering English in the 14th century through Old French.
Abundantly carries the beautiful image of waves overflowing their boundaries - abundance isn't just 'a lot,' it's so much that it spills over and flows away. This watery metaphor appears in many languages, suggesting that humans universally understand plenty as something that moves and spreads, enriching everything it touches like a river in flood.
