School canteen: Buying food, drink, and snacks

🇮🇹 [ciao] is friendly and informal. In a school canteen, it's fine with classmates or staff you already know, but with unfamiliar staff many Italians would start with [buongiorno] instead.

💬 [vorrei] literally means "I would like," and it's a very common polite way to ask for something. You can reuse it with almost any item: [vorrei un panino], [vorrei un'acqua].

💬 [un] is used before most masculine singular nouns, like [un panino] or [un biscotto]. Before some masculine words starting with [z], [s] + consonant, or similar sounds, Italian uses [uno] instead: [uno zaino].

💬 [una] is the feminine singular "a." Before a feminine word starting with a vowel, it usually shortens to [un']: [una bottiglia] but [un'acqua].

💬 [d'acqua] is a shortened form of [di acqua]. Italian often drops the final vowel before another vowel, as in [l'acqua] or [un'amica].

💬 In [bottiglia d'acqua], Italian uses [di] ("of") where English often just stacks nouns: "water bottle." You'll see the same pattern in [tazza di tè] and [succo d'arancia].
