What does this sentence mean?
this english sentence really...
It told me I needed "degli" in the answer. Why? I answered Quanti anni sono il nostri. Degli puts the "il" a long way from "nostri".
I believe "degli" is needed because "l'" is the indicative modifier for "anno" (singular), so "anni" (plural) gets "gli. So "degli" is "of the" in this instance.
