Reliable → It is formed from "rely" (from Latin "religere", meaning to bind back or to trust) and "-able" (meaning capable of). The word "reliable" means capable of being trusted or depended upon.
Memory Tip
Think of being able to 'trust' ('rely') someone, and the '-able' means capable of. This helps you remember that 'reliable' refers to someone you can depend on.
