"Do we go to the theater or to the cinema?"
Translation:Mergem la teatru sau la cinematograf?
What would the sentence mean if we change "Mergem" for "Să merge"? Mulțumesc.
It woldn't make sense. Să merge is imperative and is in singular, third person.
That would be "să meargă" (not imperative, but subjunctive). "să merge" is not a valid conjugation.
