Learn Italian: Partite tardi? - Are you leaving late?

In Italian, you usually drop the subject pronouns (like io, tu, or voi) because the verb ending already tells you who is doing the action. The -ite ending on partite specifically means "you all" (plural) are doing it. It comes from the regular -ire verb partire (to leave).

How do I conjugate a regular -ire verb like partire for other people?

You take off the -ire to get the stem (part-), and then add the present tense endings. For partire, they are: io parto (I leave), tu parti (you leave), lui/lei parte (he/she leaves), noi partiamo (we leave), voi partite (you all leave), and loro partono (they leave).

Why does this translate to "Are you leaving" instead of "Do you leave"?

The Italian present tense covers both of these English meanings! Partite can mean "You leave", "Do you leave?", and "Are you leaving?". You don't need extra auxiliary words like "are" or "do" to ask the question, just a question mark and a rising tone of voice.

Is tardi plural to match the plural "you" (voi)?
