Learn Italian: Questo fine settimana andiamo al ristorante. - This weekend we are going to the restaurant.

In Italian, the present tense is frequently used to talk about near future plans. Because the sentence mentions questo fine settimana (this weekend), the present tense andiamo naturally translates to "we are going".

Why is it questo (masculine) if settimana (week) is a feminine word?

While settimana on its own is feminine, the combined phrase fine settimana (weekend) is masculine in Italian. Therefore, it takes the masculine word questo (this) instead of the feminine questa.

What does the word al mean in this sentence?

Al is a combination of the preposition a (to) and the masculine article il (the). When you go to the restaurant in Italian, you say you are going al ristorante (literally "to the restaurant").

Where is the word for "we" (noi) in this sentence?

Italian usually drops subject pronouns like noi (we) because the verb itself tells you who is doing the action. The -iamo ending on andiamo always means "we".
