The word 言语 is formed by combining two individual characters, 言 (yán) and 语 (yǔ), which both independently carry the core meaning of "speech", "language", or "to speak". This construction follows a common pattern in Chinese where semantically similar or related characters are paired to create a single, cohesive concept. The fusion does not simply add their meanings but blends them to form a nuanced term that encompasses the broader, more abstract idea of spoken language, verbal expression, or discourse as a whole, with the repetition reinforcing and solidifying the semantic field.
