A situation where someone does not accept something or refuses to agree with it.
Her nonacceptance of the proposal surprised everyone at the meeting.
Nonacceptance → It is formed from "non-" (meaning not) and "acceptance" (from Latin "acceptare", meaning to receive or take). The word "nonacceptance" means the state of not receiving or taking something, particularly in the context of rejection.
Think of 'not' ('non-') receiving something ('acceptance') — that's why nonacceptance means not accepting.
