IPA: /fiˈzɪːzəˌbɪlɪti/
KK: /fiˈzəːbɪlɪti/
The quality of being possible or achievable.
The feasibility of the project was assessed before any funding was approved.
Feasibility is formed from "feasible" (from Latin "facere", meaning to do or make) and the suffix "-ity" (meaning the state or quality of). The word "feasibility" refers to the quality of being able to be done or achieved.
Think of 'doing' or 'making' something ('facere') and the 'state of' that ability ('-ity') — that's why feasibility means the quality of being doable.
