I am looking for (empirical/theoretical) papers which examine the (L2, L3...) acquisition of agglutinative languages such as Japanese, Korean, Basque or Swahili by native speakers of Turkish (or inverse).
I know Gürel (2016) - unfortunately the studies in this volume do not focus on language learning strategies (such as intercomprehension). However, thank you for your advice!
Hi: Barış Kahraman has worked on the acquisition and processing of morphosyntax (I believe mostly on relative clauses and long distance dependencies) by Turkish learners of Japanese. You might want to take a look at his website: https://sites.google.com/site/kahramanbpapers/
