Phrases like 'Yours sincerely' will die out in the next ten years, according to new research.
A survey of 2,000 people by Barclays predicts language will become less formal due to instant messaging.
Starting a work email with 'Dear' will also soon become thing of the past, as 35 per cent describe it as 'old fashioned' and 9 per cent say its 'boring'.
Emails ending with 'Kind regards' or 'Many thanks' are predicted to be on the way out, with younger workers preferring 'cheers', 'speak soon' or 'TY' - an abbreviation of thank you.
Other phrases set to die out include 'to whom it may concern', and 'with compliments'.
