How it's used

Functions as a measure word for abstract, intangible, or extremely fine things that are barely perceptible. It emphasizes the absolute scarcity or near absence of something, often appearing in negative constructions. It is almost exclusively paired with 一 to form the fixed phrase 一絲.

Examples

There is not a trace of a smile on his face.
Do you still have a tiny bit of hope left?

Common phrases

Common mistake

Avoid using it for physical objects that are countable in a standard sense, as it is reserved for abstract concepts like hope, emotion, or light. It is not a general-purpose measure word for thin items like thread or hair.
