My Flashcards

Definition

Meaning

A sudden, potentially explosive flow of air into a fire, caused when oxygen is introduced to a space where a fire has been smoldering with depleted oxygen.

Any effect or situation where a sudden, often violent, reverse flow occurs, sometimes used metaphorically to describe a negative or dangerous consequence following an action.

Linguistics

Semantic Notes

Primarily a firefighting term. While it describes a specific physical phenomenon, it can be used figuratively, especially in political or social commentary, to denote a sudden, negative reaction to a policy or event. Different from a 'flashover' (simultaneous ignition of all combustibles in a space).

Dialectal Variation

British vs American Usage

Differences

The term 'backdraught' is the standard British spelling. The American English equivalent is 'backdraft'. Both refer to the same phenomenon, but 'backdraught' is exclusively British.

Connotations

In both varieties, the primary connotation is danger and explosive violence. The term gained wider public recognition through the 1991 American film 'Backdraft', which may make the US spelling more recognizable globally.

Frequency

The term is infrequent in everyday language. In technical/firefighting contexts, it is standard. The American spelling 'backdraft' is more frequently encountered in international media due to Hollywood influence.

FAQ

Frequently Asked Questions
