title_body: How much of Slovio is based on Esperanto?
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.
