title_body: How much of Slovio is based on Esperanto? According to Wikipedia, 
  
  
    Slovio (from the Slavic word "slovo") is a constructed language begun in 1999 by Mark Hučko. Hučko claims that the language should be relatively easy for non-Slavs to learn as well, as an alternative to languages such as Esperanto which are based more on Latin...
    [...]
    Slovio has a relatively simple grammar based on a mix of Esperanto grammar with Slavic elements. Just like in natural Slavic languages, new words can be formed with a variety of suffixes and prefixes.
  
  
  I'm not familiar with Slovio or Esperanto at all. How much is Slovio based on Esperanto? Does it just take some parts of the grammar, or does it go to a further extant than that?
upvoted_answer: In terms of the vocabulary, not much is based on Esperanto.
  
  From the Slovio website:
  
  
    Esperanto? While Esperanto is a simple language its main problem is the fact that it is made up of too many unrelated languages and thus, if you speak Esperanto, no-one will understand you only other Esperantists. On the other hand Slovio, since it is made up of only closely related Slavic languages, can be put to an immediate use. Using Slovio, you will be understood by some 400 million people, most of whom have never ever heard of Slovio, but who will understand you.
  
  
  So, it looks like the only inspiration Slovio has taken from Esperanto is the grammar.
