Today's Parola del Giorno is the expression a naso, which means off the top of one's head or at a guess.
See the expression used below:
Non siamo sicuri di quanti soldi abbiamo raccolto con la vendita dei dolci per beneficenza ma, a naso, direi che ne abbiamo raccolti parecchi, per fortuna!
We are not sure how much money we collected selling candy for charity, but, off the top of my head, I would say that we luckily collected quite a bit.
I like how you provide these everyday words or phrases which help me speak Italian. Learning Italian from a text book and or classes, you speak a very formal/stilted form of Italian using a ton of words when in everyday speech a native would use only a few.
