Spanish

Zander informed me today that his name is now Zander Dominco. I am not sure how to spell it because I don't speak Spanish or French. He has been speaking other languages now for a couple of weeks. His class has been studying other countries and he is very facinated with the other languages. However, he will not say the words that he does know in French or Spanish, he makes up his own words, or should I say paragraphs and conversations. His teacher told me today that he asked her, "Don't you understand my French?"
I wonder how long this phase will last?
