Comments:Poppe 117 (Mong.-Tung.), KW 209, АПиПЯЯ 293-294. In Jpn. one could (following Ozawa) compare *ír- 'to enter', but the latter should be rather compared with Kor. tɨr- id. (see *tire), while *ítá-r- is also a perfect phonetic match for PA *ī́re. Turk. reveals variants *ēr- and *īr- ( < *īre-?). Cf. also Koguryo *i- 'to enter' (Lee 37, Menges 1984, 267).
