Translation of dogmático

I have studied French for many hours per week, and I've even lived in Geneva for a while... my French was good than. Today, I have forgotten most of it. I have to re-learn and Vocabulix can help.
We can help each other with these language studies, this is also the main purpose of Vocabulix. I have already got in touch with some other users. I can speak Italian, but my grammar is weak.
Thanks again for your letter. For now, the weather here is like it is in your country, ice cold. I will write you a letter in Spanish and in English. So you can compare the sentences.
