Japanese and Korean are typologically quite similar, so a linguistic phenomenon in one language often has a counterpart in the other. The papers in this volume are intended to further collective and collaborative research into both languages. The contributors discuss aspects of language acquisition, sociolinguistics, pragmatics, phonology, syntax, morphology, and semantics. Most of the papers were presented at the Southern California Japanese/Korean Linguistics Conference in 1989. Hajime Hoji is a professor of linguistics at the University of Southern California.
