What is Idiom?
An idiom is a fixed or familiar expression whose conventional meaning cannot be understood fully by interpreting each word literally, such as 'break the ice' or 'under the weather.'
What good idiom looks like
Useful idioms fit the audience, region, register, and character voice. In creative or informal writing they can create natural speech, while in technical or international communication they should be used carefully because literal interpretation can confuse readers.
- A conventional phrase.
- A figurative meaning recognized by a language community.

How can editors track a source change for Idiom without reviewing the entire site?
Use persistent claim, source, and dependency records. Link only the claims that truly depend on a source, then change that source record’s status in the Writing Authority admin when it is corrected, superseded, stale, withdrawn, or retracted. The registry queues the linked claims with a reason code and priority. Reviewers can see the affected guide, inspect the source/dependency IDs, revise or replace the evidence where necessary, and close the queue item after verification. Original site-created examples and templates remain independent unless they contain a real external factual dependency.
