Qual è la differenza tra til å e å ?Sentiti libero di rispondere con un esempio.

English is the peculiar one in this instance. When one would assume "to to", it simply becomes "to". Norwegian, with its distinct words "til" and "å", treats these words normally.

Examples:
Jeg liker å løpe. = I like to run.
Bruk kniven til å kutte grønnsaker. = Use the knife to cut vegetables.

In the latter case, English uses "to" in a dual purpose as both an expression of purpose (til) and as an infinitive marker (å).

You wouldn't say "I like run."; you need the infinitive marker. If you said "I like running.", i.e. using the continuous, you don't, highlighting the distinction.

If you were to insist on imusing the continuous in the latter case, you could, albeit awkwardly, say something like "Be in a situation where you are using the knife to be in a situation in which you are cutting vegetables.". If you were to take out the "to" from this last sentence, you'll find it doesn't work anymore.
