Which one of these is correct?
- Do everyone in the show speak Spanish?
- Does everyone in the show speak Spanish?
And can someone explain when it is appropriate to use the words "do" and "does"?
Singular: use does.
Plural: use do.
Does that genius (singular) over there speak Spanish?
Do those geniuses (plural) over there speak Spanish?
However odd this may sound, everyone is singular. Thus:
Does everyone in the show speak Spanish?
It's the same as saying:
Does every single one (singular) of them in the show speak Spanish?
However (pay attention: this is crucial!), if you change it around a little bit (to plural), you'll have to use do:
Do all (plural) of those people in the show speak Spanish?
