The phrase ‘caught his eye’ is an example of figurative language known as a metaphor. In this context, the expression does not mean that someone’s eye was physically caught or held in place, but rather that something attracted someone’s attention. This figurative use enhances the language by adding a layer of imagery, suggesting that the object or situation was compelling enough to draw one’s interest strongly.
Metaphors are commonly used in everyday language to convey meaning in a more vivid and relatable manner. By comparing attention to being physically ‘caught,’ the phrase invites the reader or listener to visualize the act of noticing something captivating in a more dynamic way.
