Re: State of Languages in the Federation
I like to think that Esperanto achieved some sort of resurgence in popularity and was used as the basis for Federation Standard. Of course, since Star Trek originated in America, the language and signage is primarily American English, and current nations frequently translate the dialogue into their own languages.
I'm choosing Esperanto only because William Shatner did make a film (Incubus
) done in it.
