The Chinese word "挥手" (huī shǒu) is a compound verb formed through the combination of the character "挥", meaning "to wave" or "to brandish", and "手", meaning "hand". It follows a common grammatical structure in Chinese where a verb ("挥") is paired with its direct object ("手") to create a new, specific action, literally "to wave the hand". This verb-object (or dòng bīn) construction yields the specific meaning of waving one's hand, typically as a gesture for greeting or farewell. The formation is semantically transparent, as the meaning directly arises from the sum of its parts.
