Comments:ТМС 2, 76, АПиПЯЯ 79. Despite Poppe 1966, 198, Doerfer MT 52, TM cannot be borrowed from Mong. The irregular voicing in Jpn. ( < PA *-p-) must be due to a confusion with a very similar root, *sìmpá ~ *símpá 'firewood' < PA *sắp`í; Jpn. dialects show a great deal of confusion between these two roots.
