The word **半点** (bàndiǎn) is a compound formed by combining the character **半** (bàn), meaning "half," with **点** (diǎn), which in this context means "a little" or "a dot." Together, they create an idiomatic expression that literally suggests "half a dot," but is used figuratively to mean "the slightest bit" or "a tiny amount," almost always in negative constructions (e.g., "没有半点" - "not the slightest bit") to emphatically deny the existence of even a minimal quantity of something.
