Sarah van Eyndhoven is a Rutherford Foundation postdoctoral research fellow based within the New Zealand Institute of Language, Brain and Behaviour (NZILBB) at the University of Canterbury. Her main research interests are historical sociolinguistics, Scots, and the interactions between language and identity. She is interested in how aspects of diachronic variation and change observed in historical varieties may have been influenced by changing identities, emerging in response to major social or political changes experienced by the language community, such as migration and the formation of new geopolitical territories. Her current research focuses on the use of heritage features (Scots) and the adoption of new linguistic features (New Zealand English and te reo Māori lexis) by Scottish immigrants arriving in New Zealand during the late nineteenth century. This involves collecting and digitising the correspondence of Scottish settlers, creating the first publicly available database of early New Zealand writing, and then identifying relevant features and investigating the influences of changing identity, nationhood and social connectivity on linguistic behaviour.
