Definition gas in British English

gas noun

noun

Differences between British and American English: gas

In the UK, gas usually refers to a clear substance like air that is burned to cook food or to heat your house: a gas boiler. Gas can also have this meaning in the US, but when American speakers say gas they are usually referring to a type of liquid fuel that is used to produce power in cars: We’d better get gas on our way out of town. In the UK, you call this fuel petrol.
