The word "称作" is formed through the morphological process of compounding, where two independent lexical morphemes, each with its own core meaning, are combined to create a single, new semantic unit. The character "称" carries the fundamental meaning of "to call" or "to name", while "作" conveys the sense of "to act as" or "to regard as". Their fusion is not merely additive but integrative, semantically blending the act of verbal designation ("称") with the conceptual framing of a role or identity ("作"), resulting in the unified meaning "to be called/named as" or "to be regarded as". This formation exemplifies how classical Chinese roots combine to produce a more specific and abstract verbal concept in modern usage.
