How it's used

Functions primarily as a suffix to denote a structured system or a scientific category. It is almost exclusively found in compound words borrowed from academic or technical terminology. Unlike the verb 係, which is the copula meaning to be, this character is strictly a bound morpheme used in formal or scientific contexts.

Common phrases

Common mistake

Learners often confuse this with the common copula 係. Remember that this character is only used as part of a noun phrase representing a system, whereas 係 is used to link a subject and a predicate.
