later." Example given by Swan "It will be illegal for anyone to donate an organ to their wife, husband, adopted child, adopted parent or close friend." With nobody or no one: "No one put their hand up." Example given by Huddleston et al. "No one felt they had been misled." Example given by Huddleston et al. With an interrogative pronoun as antecedent: "Who thinks they can solve the problem?". Example given by Huddleston et al.; The Cambridge Grammar of the English language. With everybody, everyone, etc.: "Everyone promised to behave themselves." Example given by Huddleston et al. Notional plurality or pairwise relationships Although the pronouns everybody, everyone, nobody, and no one are singular in form and are used with a singular verb, these pronouns have an "implied plurality" that is somewhat similar to the implied plurality of collective or group nouns such as crowd or team, and in some sentences where the antecedent is one of these "implied plural" pronouns, the word they cannot be replaced by generic he, suggesting a "notional plural" rather than a "bound variable" interpretation . This is in contrast to sentences that involve multiple pairwise relationships and singular they, such as: "Everyone loves their mother." I never did get into that football thing', she said after everyone returned to their seat." "Everyone doubts themselves/themself at one time or another." There are examples where the antecedent pronoun (such as everyone) may refer to a collective, with no necessary implication of pairwise relationships. These are examples of plural they: "At first everyone in the room was singing; then they began to laugh." Example given by Kolln. "Everybody was crouched behind the furniture to surprise me, and they tried to. But I already knew they were there." Example given by Garner. "Nobody was late, were they?" Example given by Swan. Which are apparent because they do not work with a generic he or he or she: "At first everyone in the room was singing; then he or she began to laugh." Example given by Kolln. "Everybody was crouched behind the furniture to surprise me, and he tried to. But I already knew he was there." "Nobody was late, was he?" In addition, for these "notional plural" cases, it would not be appropriate to use themself instead of themselves as in: "Everybody was crouched behind the furniture to surprise me, but they instead surprised themself." Use with a generic
