IPA: /ˌsuːpərˈæbʌndəns/
KK: /suːpərˈæbəndəns/
A very large amount of something, more than what is needed or expected.
The garden was filled with a superabundance of flowers in full bloom.
Superabundance → It is formed from "super-" (meaning above or beyond) and "abundare" (meaning to overflow or be plentiful). The word "superabundance" refers to an overflowing abundance or an excessive amount of something.
Think of having an amount that is 'beyond' ('super-') what is 'plentiful' ('abundare') — that's why superabundance means having more than enough.
