Reconstruction talk:Proto-Japonic/warə

Alternative reconstruction?
The KDJ seems to trace trace modern to older form わろし (waroshi). Daijirin's and Daijisen's entries here on Kotobank are less conclusive, only going so far as to state that warushi and waroshi were used in parallel during the Heian. Does anyone have a source that nails this down? ‑‑ Eiríkr Útlendi │Tala við mig 00:27, 4 June 2019 (UTC)
