The learning process involves complex cognitive, emotional, and behavioural components, and language acquisition is an ever-developing skill that accumulates over time. Perception, particularly through sight, plays a significant role in learning, and visual representation often accompanies the language learning process. As such, this article aims to emphasise the importance of visual stimuli in language acquisition, discussing the interpretation and classification of illustrations and their role in teaching. Visual materials, such as images, are integral to the teaching-learning process, facilitating communication and making concepts more memorable for students. Although visual materials are valuable, there are drawbacks, and teachers must carefully select and analyse them to avoid confusion or distraction. This is also discussed and explained to help teachers and learners adopt a more efficient outlook on learning a foreign language.
