IPA: /ˈfiːzəns/
KK: /ˈfiːzəns/
The act of doing or performing something, especially in a legal or formal context.
The feasance of the contract was completed on time.
Feasance is derived from the Old French word 'faisance', which comes from 'fais-', the stem of 'faire' (meaning to do or make) and the suffix '-ance' (indicating a state or quality). Thus, feasance refers to the act or state of doing or making something.
Think of 'doing' ('faire') something and the state of that action ('-ance') to remember that feasance means the act of doing.
