Comments:Mong. s- points to a following front vowel or diphthong, so one should reconstruct *ši̯ā-; in TM *-ā- and -ia- are frequently neutralized after a palatal. Jpn. *sitǝki = Kor. *stǝ́k; both forms reflect a derivative with a velar suffix (*ši̯āt`i-k`V 'smth. burned, baked'); borrowing Jpn. < Kor. or Kor. < Jpn. is not excluded (see Martin 1996, 45).
