I was wondering what the general take is on concord with they as a gender-neutral 3rd person singular pronoun. I assume there are no hard and fast rules here yet, seeing that this is a fairly new phenomenon – or am I mistaken here? If there is, indeed, an established rule, please let me know! But if there isn't, what is your view? Do you think grammatical meaning should determine concord (example [1]), or do you think semantic meaning should determine (example [2])?
[1] If someone wants this, they have to let us know
[2] If someone wants this, they has to let us know
I can't help it – [2] makes me cringe... even though I realise that there are equally good arguments for either.
What's your view? :)
