Abstract
This paper discusses a problem or problems which occurs while using prepositions in English since there is no clear-cut logic in selecting them. It tackles some controversial points concerning prepositions, such as how and when they can form a pair or pairs with a given verb, whether or not they can come in isolation at the end of a sentence, and how to make other parts of speech not to occupy their position. The purpose of this paper is to show the perplexity of using prepositions especially for EFL learners including Iraqi ones.
