Reconstruction:Proto-Japonic/karasu

Etymology
Likely onomatopoeic.

Pronunciation

 * Accent class: 3.6a (?)
 * The accentual correspondences between the Japanese dialects are irregular; The Kyoto accent pattern in the Heian period is, which suggests accent class 3.6. Tokyo has an irregular accent pattern  ; such accent pattern only goes back to the now rejected accent class 3.3. Kyoto has conflicting accent data; the Nihon Kokugo Daijiten gives   for Kyoto, but Hirayama (1960)'s Zenkoku Akusento Jiten gives   for Kyoto. The former accent in Kyoto would be 3.1, but the latter would give an accent class of (3.3,) 3.4, or 3.5. Kagoshima has   accent, which goes back to the Proto-Japonic low register (3.4, 3.5, 3.6, and 3.7), and that also applies for Proto-Ryukyuan, which can be reconstructed with a tone class C, which also goes back to the aforementioned Proto-Japonic low register.
 * Note that Martin (1987) also reconstructs accent class 3.6, based on more accentual data, to which we can integrate the Proto-Ryukyuan tone class data to apply the subclass 3.6a.
