That’s what I thought @Skaggfacemutt, that’s why I thought it would be interesting to see a working example of the use of “themself”, something even my spellchecker (despite not being capable of consisting of all the words in the English language) fails to pick up as being correct.
The question addressed in this article is whether ”“themself”” can be used in some cases instead of ”“themselves”” with reference to a singular ”“they”” or a singular indefinite antecedent.
