How it's used
Functions primarily as a bound morpheme in Cantonese rather than a standalone adjective. It carries a sense of instability or unpredictability, often appearing in reduplicated structures like 忽冷忽熱 to describe fluctuating states or moods. Unlike 突然, which acts as an adverbial modifier, 忽 is almost exclusively found within compound words.
Examples
He is hot and cold, I do not know what to do.
Related words
Common phrases
hot and cold (mood or temperature)
Common mistake
Avoid using 忽 as a standalone adjective to mean sudden, as it will sound unnatural or archaic. Always use 突然 or 忽然 for the adverbial meaning.
