The Chinese word "吸烟" is formed by combining two characters: "吸", which means "to inhale" or "to suck", and "烟", which means "smoke" or "tobacco". Together, they create a compound word that literally translates to "inhale smoke", directly depicting the action of drawing smoke into the mouth and lungs, typically from a cigarette or similar substance. This formation relies on the semantic contribution of each character, where "吸" conveys the method and "烟" specifies the object, resulting in a clear and intuitive representation of the act of smoking.
