Esperanto itself is mostly derived from/reminiscent of English, Polish, Russian, German, French and various romance languages (or so I’ve heard). In a post-apocalyptic future where the survivors banded together and began to communicate using Esperanto as an easy-to-learn common language, could you expect any of the far-future societies descended from these survivors to be speaking some kind of pidgin Esperanto that’s looped back around to sounding like any of the languages Esperanto is based on?
Something that has different rules and vocabulary but enough of the same sounds that an unknowledgeable observer could mistake it for garbled English or Latin, perhaps?
Or could it even be possible that the language might evolve/devolve into a straight up clone of one of these component languages?
What do you think? How plausible is it for far-future Esperanto to mutate into something that would sound vaguely recognizable to listeners today?
