What is a preposition?

• A preposition is a word that is used to link nouns, pronouns to other words in a given sentence.

• A preposition usually precedes a noun or pronoun and expresses a relation to another word.

• These are small words but they are the most important ones. A preposition sits in front of its object.

The word ''above'' is defined as an extended space over. Hence the required answer is ''above''.
