"Do we need newspapers?"
Translation:An dteastaíonn nuachtáin uainn?
Bear in mind that teastaíonn X ó Y actually means "X is wanted by Y" (X is the subject of the verb teastaigh), but it is usually translated as "Y wants/needs X" (Y is the subject of the verb "want").
When you say "We want (verb)", that verb is your X. But a verb can't be the subject of another verb, so when you try to say "We want to listen to the girl", you can't say teastaíonn (verb) uainn, and the verb is moved after the preposition - Tá uainn éisteacht leis an gcailín.
