Synonym Usage

Behind, after both refer to a position following something else. Behind applies primarily to position in space, and suggests that one person or thing is at the back of another; it may also refer to (a fixed) time: He stood behind the chair. You are behind the appointed time. After applies primarily to time; when it denotes position in space, it is not used with precision, and refers usually to bodies in motion: Rest after a hard day's work. They entered the room, one after another.

Etymology

Origin of behind

First recorded before 900; Middle English behinde(n), Old English behindan; equivalent to be- + hind 1; for adverb suffix -an, cf. before

Explanation

When one thing is behind another, it's at the rear or the far side of it, possibly even hidden by it. Your shy dog might tend to stand behind you when you meet a friend on your walk. When the sun hides behind a cloud, the cloud is in front of it, and when there's fear lurking behind your cheerful smile, the grin is disguising, or covering, your anxiety. Behind can also mean "supporting," as when you're a hundred percent behind your sister's campaign for school president; or "lagging," as when you say: "Slow down! I'm way behind in this race!" Finally, behind is a gentle slang term for "buttocks."
