I find myself often winging it with “themself/themselves” and it seems to be like themselves is always colloquially correct when there are multiple preceding nouns you’re referring to…
Otherwise if there’s only one antecedent or whatever, its themself
Be gentle haha
Note vs notate. The verb form of note is note. Notate is a back-formation of notation. It refers to writing non-linguistic transcription, like musical notation or dance choreography.
