Comments:ЭСТЯ 1,154 (Turk.-Mong.), АПиПЯЯ 286. The Jpn. word poses some problems: its accent does not correspond to Turkic length, and if we reconstruct *ēŋo (as required by Jpn. *ǝ-), PT should have a closed *ạ̄. It is worth while therefore to consider other explanations of Jpn. *ǝ̀mǝ̀-p-: e. g. compare it with Mong. ojun 'thought' and reconstruct a separate protoform like *uńo.
