The study explored the effect of using the AI chatGPT to improve the learning of FL structural and semantic features among some FL learners. The participants are 62 freshmen registered at the faculty of Foreign Languages and Translation, Misr University for Science and Technology (MUST). Two groups of participants were formed: a control group and an experimental group with 31 students each. Data collection was based on the use of the pre-posttests of English structural and semantic features. The experimental group was taught the English structural and semantic features through the use of AI chatGPT, while the control group received regular instructions. For the purpose of statistical analysis, both paired samples and independent samples t-tests were employed. The findings showed the experimental group' improvement in using the English structural and semantic features compared to the control group. Pedagogically, the study recommended the inclusion of AI chatGPT in teaching English structural and semantic features to freshmen at the faculty of Foreign Languages and Translation, MUST.
