The English language is, always has been and always will be in a constant state of flux and evolution. Which is why the major dictionaries all have their annual Word of the Year unveiling. They showcase the new words that have entered common vocabulary over the last twelve months. This year the Word of the Year according to the New American Oxford Dictionary is ‘unfriend’. It is a verb, so the full form would be ‘to unfriend’, which occurs when you delete a friend from your account on a social network site. It’s gained particularly high use as a word on Facebook.
