Prof Poplack Giving Me Some Thoughts

Prof. Shana Poplack giving a master class on variationism at the University of Queensland

The frequency at which a particular variant/linguistic variable occurs may change over time, but the conditioning factors are stable.

In which case, for language change to occur at that locus of variability, something needs to happen to disrupt the transmission of those conditioning factors to the next generation.

I’m trying to unpack the diachronic consequences of long term, stable multilingual communities with balanced bilinguals making up the population. For where I am in Southern New Guinea, I feel I should read up of this, about the social networks of hunter-gatherer societies… Because there must be some effect about interaction frequency and social networks in explaining language change?
