Etymology

Origin of feasibility

feasibl(e) ( def. ) + -ity ( def. )

Explanation

Feasibility describes how easy or difficult it is to do something. When you set a goal at work, think about the long-term feasibility of accomplishing what you want. When people talk about the feasibility of a project, they’re discussing whether or not it can be achieved — how doable is it? If you want to question your dad’s unreasonable plan for painting the entire house in a weekend, tell him you should discuss the feasibility of the task. The formal sound of feasibility allows you to question whether or not it can be done — without sounding like you’re shirking your responsibilities.
