"What is your name?"

Translation: Come ti chiami?

[mtantillo]

By literal translations, I believe:

"Come ti chiami?" = "How are you called?"
"Cos'e il tuo nome?" = "What is your name?"

I think Duo just choose a poor translation here.

Would "Cos'e il tuo nome: also work?

[ziggKogg]

Why doesn't it work?

[Quazar]

I didnt try it

[ziggKogg]

Oh I know it doesn't work I was asking other people why it doesn't work :P

[JxPatrizia]

chiamarsi = to call oneself. SO: come ti chiami = how do you call yourself?

Duo hasn't explained the formal you yet. If you are addressing an adult stranger, the polite way to ask their name is: come si chiama

If one is in a business meeting, a convention or even a shop, it is considered polite to use the formal; until the person tells you it is not necessary.

penso che funziona meglio "come" e non "cose"
come ti chiami? com'è il tuo nome?

[formaggiamente]

"Cos'è il tuo nome" shouldn't work. "Qual'è il tuo nome?" might work, though.

[Ispirac]

You can also say "come si chiama?" it is more polite version if you don't know other man.

[omer_the_bright]

why is 'Come te chiami' incorrect? aren't ti and te interchangeable in this case?

[ziggKogg]

I also reported this sentence because it popped up in http://www.duolingo.com/word_practice/it/si/Pronoun but it doesn't use "si".

[Pataglu]

I guess one can say "come tu ti chiami" then. Is it a right guess ?

[doitokatuk]

i think that it should be added as a correct answer "Qual è il tuo nome?"

[Tallman69]

One thing I find curious is Italians apparently ask HOW you are called rather than WHAT you are called, which is most common in English.
