The word 超过 is formed by combining two characters that each convey a related action of moving past a boundary: 超 means "to surpass" or "to leap over", and 过 means "to pass" or "to cross". Together, they create a compound where the meaning of the first character (超) is intensified and specified by the second (过), resulting in the unified concept of "exceeding" or "going beyond" a certain limit, as if one action completes and reinforces the other.
