You know what I find really jarring about when there's a conlang or a different species in fantasy or scifi TV or film?
They clearly don't give the actors and instruction on pronunciation. They just cut them loose and you get actors who all have their individual takes on how to pronounce a word so they all say the word differently. Drives me absolutely nuts. Hire a linguist or a speech pathologist for a day as a consultant and get your pronunciations on the same page, please.
I don't make conlangs, I focus on important things in my world building. Like climate cells, warm/cold water currents, and predicted rainfall patterns.
And yet there's always a Mediterranean, Europe, and Middle East
you learn just enough linguistics to make a language skeleton with consistent names that don't sound like 1) english but not or 2) what an english person thinks language X sounds like where X is Arabic for people in an arid climate, etc. this is much less complex than making an entire language with a full enough dictionary to express complex thoughts and grammatical rules just to have names for places
