IPA: //nɒnəˈtʃiːvmənt//
KK: /nɑnəˈtʃivmənt/
A situation or result where a goal or objective is not reached or accomplished.
The project was considered a nonachievement because it failed to meet any of its targets.
Nonachievement → It is formed from "non-" (meaning not) and "achievement" (from Old French *achever*, meaning to complete or finish). The word "nonachievement" refers to the state of not having achieved or completed something.
Think of 'not' ('non-') and 'completing' something ('achievement') — that's why nonachievement means not having completed something.
