I think English is the most irregular language in the world. Especially due to its phonetics, pronouciation and spelling. English grammar though is not so difficult, I think.

Only French, I guess, has more difficult phonetics. If you open Russian or German or Latin dictionary you see no transcriptions or so. If you open English dictionary - you do.

So, I believe, learning Russian, German or Latin is easier than English.
When I heared native Italian speech I was able easily separate and understand words, but when I hear native English speech, I dont.

By the way, I think English much more far from other German languages than they are from the each other. So, I guess, It will be another "Anlo-Saxon" language family in the nearest future.

Besides, there are many German words in Russian, for example, солдат, патруль, пароль, патрон, вагон, вокзал, шторм, штиль, штык, штаб, эрзац, матрас, штамп, ранг, горн, флаг, штат и т.д.
