As we have seen in previous instances of this blog post series, there are many parallels but also many differences between the evolutionary branches of biology and of linguistics. In the following, I will present a comparison of the causes due to which two related inheritable entities (e.g. two words or two genes of different languages or species) may differ from each other, or two unrelated ones resemble each other. The linguistic categories presented here can also be found in List (2016) whereas the biological categories are largely based on Koonin (2005).
The blog post introduces ideas discussed in our project about taking a closer look at word formation from a semantic (or semasiological) point of view. Since this so far underinvestigated approach to word formation processes lacks proper terminology, a new term to denote the central research question of concept-based type-frequency is introduced and contrasted with related established terminology.
