This document discusses challenges in teaching prepositions to English language learners. It begins by noting that prepositions are difficult for non-native English speakers to master due to issues like polysemy and interference from the learner's native language. The study aims to identify difficulties English teachers face in teaching prepositions and how prepositions are addressed in textbooks. A questionnaire given to 50 English teachers found that most feel prepositions are challenging to teach, textbooks provide little instruction, and the most common student error is transferring prepositions directly from their native language.
