Yes, it's true in some degrees. but the conjugation of verbs of spanish is more complex than that of english

I think that it depends on what your mother tongue is, for the most part. For example, you would have a much easier time learning Italian than I would, as Spanish and Italian are both derived from Latin. That being said, however, I do feel that if I had a different native language (other than English), I would find English pronunciation to be much more complex than Spanish pronunciation. Spanish pronunciation is very logical, and just "makes sense" for the most part :) You have a very beautiful native language!

When you are already accustomed to one language, it is just as hard to learn another however simple the pronunciation is. Spanish has just 5 vowel sounds but I can't tell you how many times I have messed up the pronunciation. For instance, It took me years to start saying "debería" instead of "debuhría".
