runoff
B2Formal, Technical, Journalistic
Definition
Meaning
An extra race, competition, or election held to decide a winner when the initial contest ended in a tie or without a decisive outcome.
1) Water from rain, snowmelt, or irrigation that flows over the land surface (surface runoff). 2) The draining away of water or substances carried by it. 3) A smaller, final contest after the main one to determine a definitive result.
Linguistics
Semantic Notes
Three primary, distinct meanings: 1) hydrological/ecological, 2) political/electoral, 3) sporting/competitive. Meaning must be deduced from context.
Dialectal Variation
British vs American Usage
Differences
Both dialects use all three meanings. The hydrological sense is universal in technical contexts. The electoral 'runoff (election)' is more frequent in US politics due to common electoral systems requiring a majority, whereas UK 'second ballot' or 'run-off' (with hyphen) is used.
Connotations
Hydrological sense often carries negative environmental connotations (pollution). Electoral sense is neutral/procedural. Sporting sense is neutral.
Frequency
In everyday news, the electoral sense is highly frequent in US media. The hydrological sense is common in environmental/science reporting globally.
