A subtle dialect developes among yinrih when writing English. Since the first humans that the crew of the
Dewfall meet and befriend are hams, some old-timey telegrapher slang finds its way into the everyday English of other yinrih. This includes “HI HI” for “

”, “R” (whence “roger”) for “OK” or “understood”, and “fine business” for “that's nice” or “sounds good.” Occasionally you'll see “73” for “goodbye”.
