Able to be achieved or obtained; something that can be reached or accomplished.
Setting realistic goals makes them more attainable.
Attainable is formed from "attain" (from Old French *atteindre*, meaning to reach or achieve) and "-able" (meaning capable of being). The word "attainable" means capable of being reached or achieved.
Think of being able to 'reach' something ('attain') — and the '-able' means it can be done. This helps you remember that 'attainable' refers to something that can be achieved.
