At the end of the day, it’s not rocket science

A top 10 of irritating expressions has been compiled by researchers at Oxford University.

Heading the list was the expression 'at the end of the day', which was followed in second place by the phrase 'fairly unique'.

The tautological statement "I personally" made third place – an expression that BBC Radio 4 presenter John Humphreys has described as "the linguistic equivalent of having chips with rice."

Also making the top 10 is the grammatically incorrect "shouldn't of", instead of "shouldn't have".

The top ten most irritating phrases:

1 - At the end of the day

2 - Fairly unique

3 - I personally

4 - At this moment in time

5 - With all due respect

6 - Absolutely

7 - It's a nightmare

8 - Shouldn't of

9 - 24/7

10 - It's not rocket science
