Prepositions are small words that serve important functions in the meaning of sentences. They show relationships between persons, objects, places etc. They also act as vital markers to the sentence structure. This descriptive analysis measured and analyzed the common errors of 44 grade 9 students in the use of prepositions using an objective test. Using the measures of central tendency, particularly the mean, the study revealed that the students had more errors in prepositions of direction. Moreover, the students tend to choose inappropriate prepositions that are out of context. The results showed that students were confused with the multiple functions of prepositions. English teachers, on one hand, should review their students on how to make distinction among the rules of different prepositions and apply effective learning strategies in teaching them.
