I had english as first foreign language since 5th grade.
I had to chose a second one. I wanted to learn latin, but there were not enough people.
So I had to chose between french and russian. I chose french because it has the same letters as german and english.
German and latin are complicated but also logic. (OK, there are many strange things in german and I do not know latin.) I have no problems with complicated things as long as they follow some logic rules. Please remove all irregular verbs out of all languages
I have heard that iran has the most simple language. But I do not know it.
