Cf. perhaps also MKor. jǝ̄t 'now' ( < *jǝ̄r-t = Mong., Turk. *erte?); Lee 1958, 108 also draws MKor. ǝri 'time, season', ǝrɨn 'quickly', which we were unable to identify. Borrowing in Mong. from Turk. (Щербак 1997, 116) is hardly plausible: the *-t`V suffix in this case must be Common Altaic. The etymology is still quite valid, despite all attempts of Doerfer (TMN 4, 257-259). Cf. also Turk. *er-k- 'early; ancient' = Mong. argi- 'to be old, ancient, mature'.
