"Ми слухаємо радіо."

Translation: We listen to the radio.

[kyrcant]

"we listen to radio" is a perfectly natural sentence. in this context, radio means not the object, but the programs or music that are being broadcast.

EXAMPLE
"Do you listen to CD's in the car?"
"No, I listen to radio."

[Riaz032]

How to say ' we are listening to the radio'?

[Jenni7771]

I say "we listen to radio" or it could be "we listen to the radio" . Not exclusively a radio. A.

[sagitta145]

I think both "a" and "the" should be accepted although "the" is more common, but "We listen to radio" is wrong.

[GeneM.]

I've seen ця for use with feminine nouns. But I'm not familiar with цю. When is it usually used?

[sagitta145]

Цю is the accusative form of ця.

Ця машина моя (Nom)

Я маю цю машину. (Acc.)

Цій машині три роки. (Dat.)

and so on, just like Latin...

[GeneM.]

Thank you!
