'abounder' originates from the verb 'abound', which comes from Latin, specifically the word 'abundare', where 'ab-' meant 'from' and 'unda' meant 'wave'.

'abundare' transformed into the Old French word 'abonder', and eventually became the modern English word 'abound'.

Initially, it meant 'to overflow or be plentiful', and this meaning has largely remained the same in modern usage.
