Fake news, a term popularised by U.S. President Donald Trump, has been named the word of the year by Collins dictionary due to its widespread use around the world. The U.K.-based lexicographer found that the use of “fake news” registered a 365% rise in the last 12 months.

Defined as “false, often sensational, information disseminated under the guise of news reporting”, fake news takes over from Brexit — which was named the definitive word last year after the June 2016 referendum in favour of the U.K.’s exit from the EU.

“Fake news, either as a statement of fact or as an accusation, has been inescapable this year, contributing to the undermining of society’s trust in news reporting,” said Helen Newstead, Collins’ head of language content.
