The Oxford English Dictionary has one-upped Theresa May over her definition of Brexit.
In one of her speeches shortly after becoming Prime Minister, May famously declared that "Brexit means Brexit", but now the Oxford English Dictionary (OED) has made its own definition for the noun.
In the dictionary, "Brexit" is now defined as "the (proposed) withdrawal of the United Kingdom from the European Union, and the political process associated with it".
The definition also says: "Sometimes used specifically with reference to the referendum held in the UK on 23rd June 2016, in which a majority of voters favoured withdrawal from the EU."
The OED made reference to the "impressive" speed in which the word became widely used.
