Able to be accepted or confirmed as satisfactory or valid.

Approachable is formed from "approach" (from Old French *aprochier*, meaning to come near) and "-able" (meaning capable of being). The word "approvable" means capable of being approved or accepted.
Think of something that can be 'come near' ('approach') and is 'capable of being' accepted ('-able'). This helps you remember that 'approvable' means something that can be approved.
