Despite empirical evidence from research showing that the use of text-picture combination is beneficial for second language (L2) learning, little is known about the effectiveness of reading comic books for incidental vocabulary acquisition. This study investigated the effects of engaging with comic books on incidental learning of L2 Italian vocabulary. Using a pretest-posttest design, we collected data from 35 Iranian learners of Italian as a foreign language, 25 of whom read and then read while listening to four comic books in a four-week period. Additionally, after reading each book, students completed two follow-up meaning-focused activities focusing on learners' unprompted use of vocabulary. The results revealed that engaging with comic books was beneficial for incidental vocabulary acquisition. The findings suggest that comics are a valuable and effective source of language learning, and their inclusion in L2 teaching and learning can be particularly advantageous to L2 learners, including novice learners.
