“Quick question: Is “themself” gramatically correct? I was just wondering, because “themselves” sounds wrong when someone says it to me.”
Great question, Anonymous! I have heard people use both themself and themselves in place of himself or herself for a singular they user.
My understanding is that themselves is grammatically correct, because for an unknown person we would use themselves, like “maybe the FedEx driver thought they should open the door themselves to leave the package” etc. When using singular they for a known person, it follows grammatically that we also would use themselves.
However, I’m more faithful to peoples’ feelings and needs than I am to Standard English grammar. So, what I think is happening is that people are trying to modify singular they usage to make it more apparent sometimes that they are speaking about a single person. So, ‘themself’ is emerging.
I like singular they for its seamlessness, and themself is aurally jarring, so I imagine I’ll continue to use themselves unless asked to do otherwise.
I’d love to hear from others about this!
All the best,
