How it's used
While 迅 is a common morpheme in formal compounds like 迅速, it is rarely used as a standalone adjective in spoken Cantonese. Native speakers almost always prefer 快 or 快捷 when describing speed in daily conversation. Using 迅 on its own can sound overly literary or like a deliberate attempt to sound archaic.
Examples
He ran so fast that he disappeared in an instant.
This happened so quickly that everyone was caught off guard.

Common mistake
Learners often try to use 迅 as a direct replacement for 快 in casual speech, but this sounds unnatural and stiff. Stick to 快 for everyday speed and reserve 迅 for formal writing or specific compound words.
