Learn Italian: Scusa, non ho capito. Puoi ripetere, per favore? - Sorry, I didn't understand. Can you repeat, please?

Scusa is the informal way to say "sorry" or "excuse me", used when talking to a friend, a family member, or someone your own age. If you are speaking to a stranger, an older person, or someone in authority, you should use the formal version: Scusi. Because this sentence uses scusa, we know the speaker is talking to someone informally, which is also why they use the informal puoi (you can).

Why does it say ho capito instead of just capisco?

Capisco is the present tense meaning "I understand". To say "I didn't understand" (in the past), Italian uses a past tense called the passato prossimo. This is built with a helper verb plus an action word. Here, it's ho (I have) + capito (understood). Literally, the sentence means "I have not understood."

If a woman is speaking, does capito change to capita?

No, it stays capito. When you form the past tense using the helper verb avere (to have), the second part of the verb (the past participle) almost always ends in -o, regardless of whether the speaker is male or female.

Why does ripetere end in -ere instead of being conjugated for "you"?
