How it's used

Used primarily in mechanical and automotive contexts, this term is a direct technical loan from written Chinese. While it is the standard word for the component, most casual speakers might simply refer to it as part of the engine or motor unless they are specifically discussing mechanical repairs.

Common mistake

Do not confuse this with the verb 活塞 used in some other contexts, as it is strictly a noun in Cantonese. Learners often struggle with the measure word, so remember to use 條 for this cylindrical component.
