Something that can be argued against or disputed.
The results of the election are contestable, and many people are questioning the outcome.
Contestable → It is formed from "con-" (meaning together) and "testari" (meaning to witness or testify) and the suffix "-able" (meaning capable of). The word "contestable" refers to something that is capable of being witnessed or challenged, implying that it can be disputed or argued against.
Think of something that can be 'witnessed' or 'challenged' ('testari') together ('con-') — that's why contestable means it can be disputed.
