A competition judge once pulled me up on using the word ‘that’ (instead of ‘who’) when referring to a person. It was the last time I made that mistake!
The word ‘self’ in ‘yourself’, ‘himself’, ‘herself’, ‘itself’ is a reminder that these pronouns are meant to be used only when the action reflects onto the actor. I cannot contact ‘yourself’, but I can contact ‘you’.
As a traditionalist, I think that using ‘they’ as a gender-neutral singular pronoun is just a slack way of making your text inclusive, whether for marketing reasons or out of fear of being considered politically incorrect.
On a fine January day, during the women’s singles final of the Australian Open tennis tournament, there was an incident. This incident involved a line call, a corrected line call, a chair umpire…and a conspicuous grammatical error.
