We have always studied, in English Reflexive Pronouns, that for singular, we should use 'self':
I = myself
you = yourself
he = himself / she = herself / it = itself
you = yourself
he = himself / she = herself / it = itself
Instead, for plural, we should use 'selves':
we = ourselves
you = yourselves
they = themselves
you = yourselves
they = themselves
However, I have heard "themself" a few times and seemingly, for the same reason: to obviate the need for gender explicit pronouns.
Let's go to make a review:
- "Themselves" is the reflexive pronoun traditionally used in the third person plural. Ex.: They hurt themselves while playing football.
- More recently, "themselves" has been used as a gender-neutral pronoun to refer to a single person and avoid the cumbersome "himself or herself" phrase. Ex.: Somebody hurt themselves while playing football. (You want to avoid specifying if the "somebody" is male or female.)
- Traditional English grammar would have the above sentence as: Somebody hurt himself or herself while playing football.
- The use of themselves as a reflexive pronoun to refer to a single person is widespread, but considered by some as incorrect on the grounds that a plural cannot be used for just one person. So, people started using "themself" instead. Ex.: Somebody hurt themself while playing football.
The shorter OED (Oxford English Dictionary) offers this thought : "Use
of themselves to refer to a single person of unspecified sex is now
becoming acceptable : see note at they . The apparently more logical
form themself is not widely accepted , however ."
