Subsection Terminologies in Northern Australia: Conceptual and Lexical Diffusion

Default lexical diffusion involves diffusion of phonological forms and their associated semantics. Subsections are a domain in sociocentric kin classification, whose spread shows full, partial, and null matches between conceptual diffusion and diffusion of terminologies. This offers a rare opportunity to analyse correlations between conceptual and linguistic diffusion. These correlations are modelled using social network theory: partial conceptual diffusion correlates with rapid increase in weak ties: partial lexical diffusion with lesser change in weak ties. Subsection terminologies are widely diffused, and are therefore wanderwörter. However, they constitute a distinctive subclass as a lexical domain is diffused and not individual words.
