This study explored the interplay of personality, learning strategies, and learning environments in achieving success in Arabic grammar learning. A narrative inquiry approach was employed, with participants purposively selected based on their outstanding achievements in Arabic grammar competitions. Data were collected through in-depth interviews, and participants’ experiences were reconstructed and interpreted for analysis. The findings indicated that, in addition to effective instructional management and well-structured curriculum design, the integration of constructive personality traits, strategic learning approaches, and supportive learning environments significantly contributed to learners’ success in mastering Arabic grammar.
