Intolerable → It is formed from "in-" (meaning not) and "tolerare" (meaning to bear or endure) and the suffix "-able" (meaning capable of). The word "intolerable" means not capable of being endured or borne.
Think of 'not' ('in-') being able to 'bear' ('tolerare') something — that's why intolerable means something you cannot endure.
