The Chinese word 三角 is a compound word formed through semantic combination. It consists of two characters: 三 (sān), meaning "three", and 角 (jiǎo), meaning "angle" or "corner". When combined, they create a direct, literal meaning of "three angles", which is the standard term for a geometric triangle. This formation is a typical example of a logical, descriptive compound in Chinese, where individual meaningful components are joined to denote a new, specific concept.
