What does Nombre de tu calle mean?

'Tu nombre' means 'your name.'

Remember that 'tu' is often used as 'your' for someone with whom you are familiar or friendly; to ask for someone's name who you do not know well or you wish you to accord respect, it is often better to say 'su nombre' for usted.

Be careful! While 'nombre' sounds like the English Word 'number,' it is not a cognate - so it does not mean the same thing in English. 'Nombre' is 'name' while 'número' is 'number.'
