Old Korean and Proto-Korean *r and *l Revisited
Abstract This article argues for new internal evidence for the existence of the contrast between *r and *l in Old Korean and Proto-Korean on the basis of the Hyangchal data and Old Japanese transcriptional glosses as well as Korean loanwords in Manchu and Jurchen that were not analyzed in this way before. Namely, I will argue that combined Old Korean and Middle Korean data call for the reconstruction of two different types of liquids in the position before *i: both stay intact in Old Korean, but in Middle Korean the first type undergoes elision, whereas the second type stays intact. I then attempt to identify these two types on the basis of the internal evidence and parallel phenomena attested in the Greater Manchuria linguistic area and elsewhere.
