Learn Italian: Potresti aggiornare la password del computer? - Could you update the computer's password?

Potresti is the conditional form of potere (to be able to), meaning "could you". At this level, you will often see the conditional used to make polite requests. It softens the question from "Can you?" (Puoi?) to the much more polite "Could you?" (Potresti?).

Why is aggiornare left in its dictionary form instead of being conjugated?

Because it follows potresti. When you use a modal (helper) verb like potere (can/could), volere (want), or dovere (must), only that first verb changes to match the speaker. The second verb always stays in the infinitive (dictionary) form.

Is there a trick to remembering the word aggiornare?

Yes! If you look closely at aggiornare, you will spot the word giorno, which means "day". Literally, it means to bring something up to the current day. This is a very helpful trick to remember that it means "to update".

Why is password feminine (la password) when most English words in Italian are masculine?
