Rej

REJ is an acronym and code that can refer to several different terms depending on context. There is no single, universal meaning for REJ, but it appears in language coding, technology, and organizational contexts.

One notable use is as the ISO 639-3 language code rej, which designates the Rejang language. Rejang is an Austronesian language spoken by the Rejang people in parts of Sumatra, Indonesia. The language has multiple dialects and a historical tradition of writing in the Rejang script, though Latin script is common in modern communication.

In technology and data processing, REJ is sometimes used as an abbreviation for “reject” or “rejection.” In this sense, it may appear in logs, error messages, validation outputs, or protocol exchanges to indicate that a particular item did not meet criteria or was not accepted by a system. The use is informal and varies across software and hardware platforms.

Beyond these uses, REJ can appear as an acronym in various organizational names, project titles, or codes, reflecting different languages and domains. Because the term is not tied to a single widely recognized entity, its meaning is typically inferred from surrounding context.
