Proto-North Caucasian: *thwǝ̆mV
Meaning: seed; stem, spadix
Notes: Reconstructed for the PEC level. The root is of Iranian origin (cf. Avest. taoxman- 'seed; kin', Pers. tuχm id. < PIE *teuk-men-), but must have been borrowed very early, because modern reflexes can not be deduced from late Iranian forms, and have considerably changed semantically and phonetically.
