Root Explanation
Treatability → It is formed from "treat" (from Old French *traiter*, meaning to handle or deal with) and "-ability" (meaning the quality of being able to). The word "treatability" refers to the quality of being able to be treated or handled in a certain way.
Memory Tip
Think of the ability to 'handle' or 'deal with' something — 'treat' means to deal with, and '-ability' means the quality of being able to do so.
