Borrowed from Persian دفتر‎ (daftar), ultimately from Ancient Greek διφθέρᾱ (diphthérā, “parchment”). There is also an irregular spelling with གཏེར (deb gter) based on a 'folk etymology' connecting it to the meaning "treasure", due to the accidental similarity of the the Persian-Greek words tar/thérā with the Tibetan word. Thus it appears that this Greco-Persian etymology is also the origin of deb, the main Tibetan word for "book", as the monosyllabic deb is derived from the longer word deb ther. [Erick Tsiknopoulos]
