it means: I also speak spanish
Yes, I speak spanish ;)
It means "you speak Spanish too.
'Se' and 'hablo' don't go together. This is grammatical gibberish. The correct expressions are either 'Se habla español' or 'Yo hablo español.' The former means "Spanish is spoken," and the latter...
This means 'I do not understand you,speak Spanish to me!' or it also means 'I don't understand ,I only speak Spanish.'
hablo* español= I speak Spanish. do you mean "habla" or "hablar"?
