The Chinese word 中年 (zhōngnián), meaning "middle age", is a straightforward compound formed by combining two characters: 中 (zhōng), meaning "middle" or "center", and 年 (nián), meaning "year" or "age". It follows a common grammatical structure in Mandarin where two meaningful characters (morphemes) are joined to create a new, specific concept, in this case, literally "middle years". This formation is purely semantic and descriptive, directly reflecting the life stage it denotes, without phonetic or symbolic complexity, though it carries significant cultural weight regarding societal expectations and personal reflection during that period of life.
