Something that can be criticized or is open to disagreement.

Exceptionable → It is formed from "except" (from Latin "excipere", meaning to take out or exclude) and the suffix "-able" (meaning capable of being). The word "exceptionable" means capable of being excluded or taken out, often used to describe something that is objectionable or open to criticism.
Think of something that can be 'taken out' ('except') and is 'capable of being' criticized ('-able'). This helps you remember that 'exceptionable' refers to something that can be objected to.
