"She was looking in through the window."

Translation: Hun kiggede ind gennem vinduet.

[tobyponz]

Wasn't this sentence an example, in present tense, of the use of ad vs af? So would this work as "Hun kiggede ind ad vinduet"?

[mizinamo]

That's what I entered and it was accepted.

[londoncallling]

I think so, yes

[Sawteeth]

Why is i gennem wrong?

[vincetier]

I=masc. Vinduet needs ind (neutr.)
