How it's used

While 能 is a common morpheme for energy in scientific terms like 熱能 or 動能, it also functions as a suffix in colloquial speech to describe personal capability or efficiency. When used to describe a person, it often carries a slightly sarcastic or critical tone if the negative form 冇能 is used. It is distinct from the Mandarin usage where 能 acts as a modal verb for ability, which in Cantonese is usually expressed by 識 or 能夠.

Examples

This machine is very energy-efficient and doesn't use much electricity.
You are so incompetent at work, how can you possibly get things done?

Common phrases

heat energy
kinetic energy
energy-saving

Common mistake

Learners often confuse 能 with 能夠 when trying to express ability. In Cantonese, 能夠 is a formal word mostly used in writing, whereas in spoken conversation, 識 or 得 are the natural choices for expressing capability.
