Some Korean-Japanese comparisons involving Japanese coronals complicate the internal reconstruction of pre-Old Japanese. Post-OJ verb forms that end uniformly in, for example, ki have distinct OJ final syllables (ki ≠ kwi) according to the form or paradigm of the verb. This is not true for OJ syllables like ti, but scholars have assumed that pre-OJ *ti ≠ *twi, etc., were distributed in corresponding verb forms in the same way as OJ ki ≠ kwi, etc. Whitman, however, has introduced K-J etymologies requiring that pre-OJ *ti > si, *ri and *ni > i, and hence that all OJ ti < *twi, etc. These conflicting results can be resolved if other pre-OJ sound changes supported by Korean etymologies are properly integrated into the internal reconstruction of Japanese verb paradigms.
