How do you say empire in spanish?

Edificio del estado imperio.

I don't know, but that song is awesome and ask your math teacher or Google English to spanish translation

To say=decir. To speak=hablar.

[Tu] no eres español. In the spanish language, you dont tend to say the ' tu'

"Do you speak Spanish" would come in two forms, depending on to whom you are speaking. For a formal tone, one would use "¿Habla usted español?". Informally, it would be "¿Hablas español?"
