Here's my guess: if it is a feminine noun that ends in 'e', then you can't add an 'e' to make it plural. So the plural has to end in 'i', even though it frustrates those of us who are learning. Hopefully someone more knowledgeable will step in and give us an authoritative answer...

Me too -- I typed "chiavi" first (the right word) then checked the audio and changed it to "schiavi" (not knowing what that means, but since that's what it sounded like, I tried it anyway) and got it wrong.
You are right - the tortoise clearly pronounces schiavi, whereas the main recording sounds correct - chiavi - so this is a recording error - hey ho...
How would one ask a female Italian real estate agent for the keys to a flat without getting slapped?
Is the "h" in hanno pronounced or is it silent. According to the voice coaching in Il Tavolo (spoken by an Italian) the "h" should be sounded.
I just took one semester of Italian and have always been under the impression the "h" is silent. Someone with more knowledge of the language can confirm that or tell me I am dead wrong!
