With the increasing global interest in learning Chinese, Arab countries have witnessed a notable rise in the number of Chinese language learners. Interrogative sentences are an essential aspect of learning modern Chinese, marked by structural characteristics that sometimes differ from those in Arabic. This study aims to examine Chinese interrogative sentences compared to Arabic and analyze how native Arabic speakers acquire them. The research relies on survey results from Arab students to explore the types and causes of errors they make. The findings indicate that primary factors include negative language transfer, rule generalization, and inadequate learning materials. The study shows that students often struggle to form questions, despite being able to answer them. To address these challenges, the research recommends analyzing learners' errors and tailoring teaching strategies according to their linguistic environment, enhancing their proficiency in using Chinese interrogative sentences.
