Proto-Altaic: *nilko ( ~ -u)
Meaning: old, grown-up
Russian meaning: старый, взрослый
Comments: A Turk.-Kor. isogloss; cf. also Kor. nɨ(l)ktari 'old beast' (see SKE 171). The parallel is striking, but one should keep in mind that the stem may be actually derived from *nàjĺV 'age', with additional influence of *jɨl 'year' in Turkic.
