An adjective that follows a noun?

You're describing a postpositive adjective. This is an adjective that comes after the noun it modifies.

Here are some examples:

* The attorney general (the noun is "attorney", the adjective "general" comes after)

* The heir apparent (the noun is "heir", the adjective "apparent" comes after)

* Anything else (the noun is "anything", the adjective "else" comes after)

Postpositive adjectives are often used:

* To emphasize the adjective: "I've never seen a house so grand!"

* To clarify the noun: "The child alone was playing in the yard."

* To form certain fixed expressions: "court martial, attorney general, heir apparent"
