Today I give a talk for the Leiden University Centre for Linguistics. The talk, ‘Moving across languages and learning traditions’, will be in 16:00 – 17:00 in Eyckhof 3/005. I will present my research on the social and cultural patterning of language learning in three multilingual African communities. In the late 1990s I was a visiting scholar in African Languages and Linguistics at Leiden University, and I am excited to see old friends and hear about the exciting work they are doing now.
