Case in point:

I am reading Earth Unaware by Orson Scott Card and Aaron Johnston. In the first chapter we are introduced to the society of independent asteroid miners in the Kuiper Belt. They have relatively closed groups of families who are spending, essentially, their whole lives in what amounts to a band level, maybe 80 or 90 people, all related to some degree or another. Marriage to anyone second cousin or closer is strictly forbidden. To marry someone in this forbidden group is referred to as dogging, the word being derived from endogamy. This etymology is explicitly pointed out in the text of the story. Later on in the chapter we get the word zogging with no accompanying explanation. We are expected to work it out for ourselves.
