• The use of themself instead of themselves is sometimes proscribed,[1] but it is relatively common "considering that singular they is unquestionably far less frequent than plural they".[2] Furthermore, the use of themself as a singular and themselves as a plural is in "clear parallel [to] common usage of the second-person forms, where yourselves can be contrasted with yourself",[3] and the same is true in the first person, where ourselves contrasts with ourself.
