Have a look at these sentences:
“The plane flew OVER Mount Everest.”
"They stood BEHIND him.”
“I stood BELOW the bridge.”
In these sentences you will notice the words in capitals are related to a noun or a pronoun. From your study of the previous two quizzes you would have surmised that these words are prepositions. The pronoun or noun that follows the preposition is the object of the preposition.
In the previous two quizzes we understood how prepositions were used to give a sense of the place, time or direction in a sentence. We also learnt that certain specific prepositions are used to convey certain specific meaning in relation to place, time or direction. Apart from conveying meaning in relation to place, time and direction a preposition is used in relation to the object of the preposition.
