How it's used
Functions primarily as a bound morpheme in Cantonese rather than a standalone noun. It appears most frequently in formal or abstract compounds like 根源 or 來源 to describe the starting point of an issue or a phenomenon. When referring to the physical source of a river or a literal spring, 泉眼 or 源頭 are preferred.

Common mistake
Avoid using it as a standalone word in casual speech, as it sounds overly literary or incomplete. Always pair it with another character to form a compound noun when expressing the concept of an origin or cause.
