A tour - fare un giro = to have a tour

That's correct but it doesn't mean just "shopping around. "Fare un giro" could have different meanings basing on the context. I think it's easier to understand through some examples: Fare un giro per negozi --> Walk around going to shops Fare un giro per la città --> Walk around visiting the city Fare un giro in macchina --> Have a small trip with a car Andiamo a fare un giro? --> Shall we go out for a walk? In any case, it refers to a movement. I hope I've helped you! :) If you need any help feel free to contact me.

Yes exactly !

Yeah, a walk around... Vivo in una città piccola e quando esco, vedo le persone che conosco in giro. Which means you see people that you know around.

Thanks!
