Comments:Lee 1958, 119 (Kor.-Mong.). Cf. also MKor. pthǝ̄k 'reason'; without vowel reduction perhaps also MKor. pùrǝ́, mod. purǝ 'intentionally, on purpose'. Mong. > Evk. bodo- etc. (see ТМС 1, 88, Doerfer MT 78). The Jpn. reflex is not quite certain, being somewhat distant semantically and aberrant accentologically (TM length should correspond to low tone in Jpn.). The voicing in modern dialects (Tok. hodo etc.) also contradicts *-t- in *pōto. One should consider a possibility of relating Kor. pthǝ̄k and PJ *pǝtua (*pǝ(n)tua) to PA *p`ḗt[e] 'name, to call' ('name' as the essence or reason of the called object?) which would be phonologically more plausible (assuming Gruntov's rule about *C`VCV > *CVC`V in early PJ).
Comments:EAS 96, Martin 249-250, АПиПЯЯ 109, 278. Korean has a frequent vowel reduction between a stop and an affricate, which makes the precise vowel reconstruction difficult.
Comments:Дыбо 10, Лексика 150. A Western isogloss. High tone is reconstructed because of Mong. *b-. The root is actively contaminating with *bŏ̀ku 'throat' q. v.
Comments:ТМС 2, 302. The root is not preserved in Turkic - but cf. perhaps the isolated Yak. buka barɨ 'all together', buka 'perhaps', buka-tɨn 'completely' (Dolg. buka 'exactly', bukatɨn 'completely', see Stachowski 64).
Comments:Laufer 1919, 575 (Doerfer: "lautlich unmöglich"). Cf. perhaps Nan. furgẽ 'loud, bass' (ТМС 2, 303). The final velar element is suffixed, and the suffixes are different here (Jpn. -k- pointing to *-k`- or -k-, but Turcic and Mongolian - to *-g-).
Comments:A Turk.-Mong. isogloss. Low tone and shortness may be reconstructed because of Mong. *h-. The root is similar to *p`út`à and *bŏ̀t`é q. v., but still should be probably reconstructed as a separate etymon.
Comments:Turk. *baĺ(č)ka 'other' is very similar, but phonetically unclear. Another irregularity is the tonal discrepancy between TM and Kor.-Jpn. (note that the TM reconstruction is not quite certain: one should perhaps reconstruct *pubuski because of the Even form, and either separate the TM form from the rest or suppose a form with a cluster like *pubsa). On the whole, a tempting but not quite secure etymology.
Comments:KW 446, Poppe 12, 52, Цинциус 1984, 52-53, Дыбо 10, Лексика 104. Despite some confusion between *pū́t`o and *p`ude, the two roots are clearly distinguishable. Kor. *pǝ̀tɨ́r must be delabialized < *pòtɨ́r.
