someone, somebody, something; anyone, anybody, anything; no one, nobody, nothing

1. Someone wants to speak to you on the phone; Someone gave me a ticket for the pop concert; Somebody gave me a ticket for the pop concert. Would anyone like a drink? Would anybody like a drink? Do yo want anything from the chemist? No one has ever given me a free ticket for anything; Nobody has ever given me a free ticket for anything. Anyone will tell you where the house is; drink anything (= «I don’t mind what I drink»).

[Los compuestos de «some,» «any» y «no» siguen las reglas de éstos.]

2. Someone’s passport has been stolen; Is this someone’s seat? Is this anybody’s seat? I don’t want to waste anyone’s time.

[«someone,» «somebody»; «anyone», «anybody;» no one,» «nobody,» y «everyone,» «everybody» pueden usarse en caso posesivo.]

3. Has anyone left their luggage on the train? No one saw Tom go out, did they? Something went wrong, didn’t it?

[Todos estos pronombres indefinidos tienen un significado singular y se construyen con un verbo en singular, por lo tanto sus pronombres personales y adjetivos posesivos deberían logicamente ser «he»/»she,» «him»/»her» y «his»/»her»; pero en Inglés coloquial se prefieren las formas plurales, «they,· «them,» ·their.» Con «something,» «anything» y «nothing» se emplea «it.»]
