Synonym discussion

Sense: noun/1

'Overdrive' suggests a person, team, machine, or system operating above its normal level, often because of pressure or urgency. 'High gear' is close and often more informal; it can describe fast, efficient activity, but it usually sounds a little less extreme. 'Rush' often focuses on a short busy period, especially when many tasks arrive at once. 'Frenzy' is stronger and more emotional, and it can suggest loss of calm or control. A newsroom before an election may be in overdrive, a shop can work in high gear during a sale, and a crowd in a frenzy sounds far more chaotic.

Etymology

Old EnglishEnglish

Built in English from 'over' and 'drive'. The mechanical sense first named a gear system that lets a vehicle keep high speed without making the engine work as hard. Later, English extended the word metaphorically to people, offices, and systems working at an unusually intense level.
