Learnability and ecological factors as motivators of language change
This chapter adopts Mufwene’s (2001) framework according to which language acquisition is a process whereby competition and selection of linguistic features from the inputs create a unique idiolect. It examines the principles of selection of a given feature over others, and the mechanisms by which a feature spreads across a community (i.e., from one idiolect to another). These questions are addressed at the individual and population levels by analysing data from a twitter corpus. The frequency of a feature in the input as well as a suggested learnability factor are relevant to this discussion. Learnability is defined as the combination of the specific linguistic properties of a linguistic feature, and the universal human capacity to learn those specific properties.
