Achievable → It is formed from "achieve" (from Old French *achever*, meaning to bring to a conclusion or to complete) and the suffix "-able" (meaning capable of). The word "achievable" means capable of being achieved or accomplished.
Think of something that is 'capable of being completed' — 'achieve' means to complete, and '-able' indicates capability.
