Cultural Tip
In Italian, "fammi sapere" is a friendly, informal way to ask for information. In a formal email or with a superior, you would switch to the formal causative: "Mi faccia sapere entro venerdì, per favore." Also, Italians often use the day of the week without an article after "entro" – saying "entro venerdì" is preferred over "entro il venerdì."
