How it's used

While standard written Chinese often uses 長時間 to express duration, Cantonese speakers frequently shorten this to 長時 in casual speech. It functions as an adverbial phrase describing the duration of an action, often placed after the verb or the verb plus the aspect marker 咗.

Examples

I have been waiting here for a long time.
Do you need to wait for a long time?

Common phrases

wait for a long time
sit for a long time

Common mistake

Learners often confuse this with 好耐, which is the much more common and natural way to express a long duration in spoken Cantonese. Using 長時 can sound slightly more formal or emphatic depending on the speaker's regional accent.
