Proto-North Caucasian: *ṭŭmhV ( ~ *ṭwĭ-,-ħ-)
Meaning: kernel,stone (of fruit,nut); marrow
Notes: The Lak. form and part of Lezghian forms are reduplicated (Lak.ṭuṭi < *ṭumṭi); otherwise correspondences are quite regular. The root must have originally meant 'kernel, fruit-stone', whence, on the one hand, meanings like "grape", "plum" and "peach", on the other hand - "marrow". Klimov (1964, 181) marks the similarity of PN *ṭum with Kartvelian *ṭwin- "brain"; it is most probable that the Kartvelian root is an old loanword from NC.
