Isn't it one of the hardest to learn? Sure, any language is nice and easy when you grow up with it, but I've always heard that English is more challenging than something like Spanish.
Sorry, it's not one of the hardest.
Spanish is harder. German is harder. Russia is harder (especially if you are non-Slovakian, that is you are not Slovakian, Polish or Chech - that, plus new alphabet to learn), Polish is really hard to learn (especially our stupid grammar - where to use 'u' and where 'ó', where 'rz' and where 'ż', because both examples are same when you talk).
Hell, even my mother knows basics of English, and last language she got to study was Russian 20 years ago. But that's because we (the previous generation) were forced to learn it.
English is easy because:
1. It has pretty simple grammar (easy - easier - the easiest and so on).
2. It's adjectives don't change when you talk about a male or female. Although, you can't say a woman is handsome.
3. Doesn't have a lot of irregular verbs or nouns.
4. Verbs change form only in 3rd person. In Spanish, German, Polish and probably more, each person has it's own change.
