It takes time to learn things like "at school" vs "at the school", "to school", "to the school", "I know English", not "I know the English", but "I know the English language" etc. etc. It's obviously easy when you speak it natively, but it just happens to be a certain way and could plausible be in another way too, as other languages show.
