The Chinese word **旋风** (xuànfēng), meaning "whirlwind" or "cyclone," is a compound noun formed through semantic combination: the first character **旋** (xuán) means "to revolve" or "to whirl," describing a circular, spinning motion, and the second character **风** (fēng) means "wind." Together, they create a meaning that is the sum of their parts—literally a "revolving wind"—efficiently and pictorially denoting a rotating column of air through straightforward descriptive compounding.
