The state of not participating or being involved in something.
The team's nonengagement in the project led to its failure.
Nonengagement → It is formed from "non-" (meaning not) and "engagement" (from Old French *engager*, meaning to pledge or bind). The word "nonengagement" means the state of not being pledged or bound to something.
Think of 'non-' meaning 'not' and 'engagement' as a pledge or commitment — so nonengagement means not being committed.
