Likewise the use of singular 'they' in place of 'his or her' or 'his' or 'her'
What would you use when speaking about someone who's gender is either unknown or non-binary?
'They' is the only thing I can think of...
I use "his or her"
I don't know what the singular non-binary pronoun is but we should settle on one and then I can use "his, her or X"
They sounds jarring to me. I know there are plenty of precedents in literature etc
There are also places where singular 'they' makes sense, e.g. - "everybody has their own opinion" sounds more fluent than "everybody has his or her own opinion"
but mostly singular they jars
"Each person chooses for themselves"
(ugh) - or worse, "each person chooses for themself"
also i get annoyed by gender neutral pronouns when there is no need for gender neutrality
eg discussing members of a women's soccer team "The player will need to get their socks" no it's "her" it's an all female team
