Some 80 people attended yesterday’s conference at Bergara by Iowa University linguist Roslyn Frank on Basque origins. You can watch the conference (in alternate Basque and Spanish languages, which she speaks very well albeit with some accent) in the following low quality video (33 mins):
The last few minutes, where she outlines possible grammatical substrate loans from Basque into Spanish and English, among other languages (Eusk. -zko > Sp. -sco, Eng. -sh, Fr. -sque), is particularly interesting, at least it’s something new to me.
