KK: /ˌpræktɪˈkæbɪlɪti/
The quality or state of being able to be done or achieved; how feasible something is.
The practicability of the new plan was discussed in the meeting.
Practicability → It is formed from "practicus" (from Greek "praktikos", meaning practical or fit for action) and "-ability" (meaning the quality of being able to). The word "practicability" refers to the quality of being practical or feasible in action.
Think of something being 'fit for action' ('practicus') and having the 'quality of being able' ('-ability') — that's why practicability means how practical or feasible something is.
