Noun
  1. 1
    A person from planet Earth.

    "Like Haiti, the Belt is dominated by a wealthy class of colonizers (in this case, Earthers who speak English). […] Some characters speak pure Belter, but most speak about half-English, half-Belter, adjusting their vocabulary for each situation. If they’re holding a separatist rally to protest Earther rule, Belter is the order of the day. If they’re trying to talk to a boss, English makes more sense."

  2. 2
    A supporter of a particular theory about the Earth. in-compounds
