The word 作为 is formed by combining two individual characters, each contributing its core conceptual meaning to create a new, composite idea. The character 作 carries the fundamental sense of "to do", "to make", or "to act", implying action or creation. It is joined with 为, which fundamentally means "to be", "to act as", or "for the purpose of", introducing a sense of identity, function, or intention. Therefore, the formation fuses the concept of purposeful action (作) with the concept of serving as or being something (为), resulting in a term that conceptually encapsulates the idea of taking on a role, functioning in a capacity, or engaging in behavior defined by a specific identity or purpose.
