| Summary:
|
Every language includes a system of kin terms but different languages carve up
the family tree in different ways. Our paper proposes a theory that helps to
explain which kin classification systems are found in the languages of the
world. We argue that kin classification systems are shaped by a tradeoff
between two competing principles: good systems are simple, and they enable
informative communication. The principles of simplicity and informativeness are relevant to other semantic domains such as color, and the tradeoff between them may provide a domain-general foundation for variation in category systems across languages.
