‖ The Turkic word is frequently regarded as a borrowing, either
from a Germanic source (EDT 628), or from an Iranian (Ossetic) source
(Аб., ЭСТЯ). The Iranian derivation of Osset. xumälläg 'hop', however,
raises some phonetic and morphological problems; on the other hand,
there are no doubts that the Turkic (Bulgarian) word was borrowed
into Mari umla, Hung. komló and Slav. xъmelь (see Егоров 192, ЭСТЯ
ibid.). The ultimate Turkic source of other late European names of 'hop'
is therefore also not excluded.
