Is it ‘his or herself’ or ‘him or herself’?

Him or herself.

To be quite correct, it should be himself or herself, although the above usage is common.

His or herself is flat wrong.

Well that seems clear enough. Thanks

I agree with palewriter that ‘him or herself is "correct," but what about the real English that has found its way forward in our daily speech: Themselves!

In the sense of: "Everyone should pick up their ticket(s) at the door."

-Or-

"I hope that anyone who is feeling ill today will kindly excuse themselves from wrestling!"

I call this the "false plural of ambiguity."

Current and tres moderne!

false plural of ambiguity

Good point, Sitran.

You could probably write a dissertation with that title and pick up a PhD.  :)   I’m still working on mine: Overlooked Quantum Physics Terminology in the Works of William Shakespeare. A thin but riveting monograph.

Wait…so
"Myself" "Yourself"
"Ourselves" "Yourselves"
yet when you reach the 3rd person it becomes the Objective, not the Genitive form which precedes -self/selves.

Yes, Palaeosophist, that seems to be the pattern for Standard English.

Other dialects, other patterns!

"Can a person really talk to themself?"

I remember a past discussion in here where somebody said:

In some dialects of Southern American English, it’s common to hear ‘his own self/her own self’, etc.
