I wonder whether Vger23 asked about Andor in
Star Wars or Andor in
The Wheel of Time, or both.
Andor is a short and simple word which is easy for humans to say. That seems like as good a reason to select that combination of sounds as a writer could want. And of course some people would interpret "andor" as having a meanng in English.
Because "andor" is easy to say, in real life "andor" should be a word and/or a name in some of the thousands of languages on Earth.
