"The window opens onto the yard."

Translation: La finestra apre sul cortile.

[jeslam42]

The window opens "out to" or "up to" sounds more correct if you ask me.

Why is " sopra il cortile " wrong ?

[willem6]

That would be literally 'on top of the yard', which is an indication of place that is incorrect here. The use of 'sul' is idiomatic here, I assume.

What is the difference between la cortile and il giardino in this context?

[ksweeen]

Giardino means garden. Cortile means yard, which I guess could contain a garden, but is generally a larger space not necessarily for growing flowers.

[emigaso5]

I suggest the translation "la finestra dà sul cortile". It's used in elegant italian.

I would have said giardino and not cortile for yard
