The word 成为 is formed by combining two individual characters, each contributing a core meaning that merges to create a new, unified concept. The first character, 成 (chéng), carries the essential idea of "completing", "succeeding", or "becoming finished". The second character, 为 (wéi), fundamentally means "to act as", "to serve as", or "to be". When joined, their meanings fuse into a single verb that conceptually depicts the process of change or development into a finalized state or role, effectively capturing the notion of "to become".
