The Times, July 27, 2017
‘Sic’ means ‘so’ in Latin, and is used when you are quoting something with an error in it to show that it is not your error. As an example, here is one of my favourite lines from a floral tribute: ‘She is with the angles (sic) now’. The Times writer may have needed to use ‘no pun intended’, even though I think it was intended.
I counsel against using the phrase ‘I could go on’, because it invites the response ‘No, please don’t.’
