How it's used

Technical terms like this are often used in their English forms in professional engineering contexts in Hong Kong. When spoken in Cantonese, the pronunciation follows the standard Chinese character reading rather than a colloquial shift. It is primarily encountered in physics or chemistry classrooms and electronics repair shops.

Common mistake

Learners often confuse this with the positive or negative terminal. Remember that the polarity of the anode can flip depending on whether the device is discharging or being charged, so it is safer to define it by the chemical reaction occurring there.
