rush hour
HighNeutral to informal; used across spoken and written contexts, common in everyday conversation and news reports.
Definition
Meaning
The two periods of the day—typically early morning and late afternoon—when traffic is at its heaviest and public transport is most crowded, due to people traveling to and from work or school.
A peak period of activity or demand in any system or context, metaphorically extending from the original traffic-related meaning.
Linguistics
Semantic Notes
The term is a compound noun. While 'rush' implies urgency and crowding, the phrase itself is a standard temporal label, not necessarily describing panic. It is used as an attributive noun (e.g., rush-hour traffic).

- It is a fixed compound; don't reverse the word order.
Common Mistakes
