5. Proper Usage of Prepositions

Prepositions are simple words but they are not as easy to use as they appear to be. Care should therefore be exercised in using them. If used wrongly, they become adverbs and conjunctions and convey different meanings as the following examples show: EXAMPLES: It was a kite that we looked above us. (adverb) I noticed an air plane above the cloud. (preposition) They waited outside the cinema for him. (adverb) The sheep are outside the fence. (preposition) We entered after her. (adverb) He arrived after we had left. (conjunction) I go jogging every day after work. (preposition)
