Learn Italian: Hanno testato la capacità del server fino a mezzanotte. - They tested the server's capacity until midnight.

The word mezzanotte (midnight), just like mezzogiorno (noon), does not take a definite article in Italian when referring to the time of day. So, you just use the simple preposition a with fino to make fino a mezzanotte (until midnight).

I see the verb testato. Is that related to the English word 'test'?

Yes! Testare is a verb borrowed from English and adapted into Italian with an -are ending. You will often see it used in technical, scientific, or IT contexts, like testing a server. In everyday situations, Italians more commonly use provare (to try or test).

The word capacità has an accent on the last letter. How would I say 'capacities' in the plural?

You do not change the word itself. In Italian, feminine nouns ending in an accented -à do not change their spelling in the plural. You just change the article: la capacità (the capacity) becomes le capacità (the capacities).

Why is it del server? How do we know the gender of English words used in Italian?
