Well, that's not a defining characteristic of English but of most (all?) living, dynamic languages. I have seen it with the languages I speak or have tried to learn (Spanish, German, Portuguese, Chinese...).
Most of those languages though change the original words to suit the language (e.g. with gendered nouns, certain suffixes, changing the spelling, etc).
English tends to just copy, at least from other latin-script languages...
