IPA: /nɒnˈæktɪŋ/
KK: /nɑnˈæktɪŋ/
Describing something that is not involved in acting or performance.
The nonacting roles in the play were just as important as the main characters.
Nonacting → It is formed from "non-" (meaning not) and "acting" (from Latin "agere", meaning to do or perform). The word "nonacting" refers to the state of not performing or not taking action.
Think of 'not' ('non-') doing something ('acting') — that's why nonacting means not performing.
