Loans and Reconstruction

Our project began with a test of the idea that hunter-gatherer and agriculturalist languages show different rates of loans. Claims are contradictory here; on the one hand, work from social network structure suggests that hunter-gatherer languages might be more resistant to borrowing than agriculturalist languages; on the other, there are claims (particularly regional ones) that because of hunter-gatherer interaction with their neighbours, their languages show higher loan rates. We tested this claim in basic vocabulary with a sample of just over 120 languages. We found that results were highly dependent on local factors; moreover, loans in the hunter-gatherer languages in the sample were, on average, no higher than for other languages.

Numerals

Hunter-gatherer languages are stereotyped as having very small numeral systems; however, our work shows that numeral systems in these languages are variable, even when they have low limits.

Workshops

We held three workshops (UTexas, Arizona, and Virginia) to discuss the project with local linguists and anthropologists, and for grant personnel to meet and work on the project.
