The term "taller" is used to describe something or someone that has a greater height compared to another object or person. For example, if you compare two trees, the one that reaches higher into the sky is considered the taller tree. This word helps us understand differences in size, especially when we are talking about people, animals, or buildings. In everyday life, we often use "taller" to describe ourselves or others. For instance, if you and your friend stand back-to-back, and you are noticeably higher, you would say, "I am taller than you." This simple comparison helps us visualize and communicate height differences easily.
