How it's used
The character 昰 is a rare, non-standard variant of 係 and is almost never used in modern written or spoken Cantonese. Native speakers exclusively use 係 to represent the copula 'to be'. Using 昰 in any context will likely be perceived as a typo or an archaic affectation.

Common mistake
Learners should strictly avoid using 昰 in any writing or digital communication. It is not a recognized character in standard Cantonese orthography and will cause confusion.
