Meaning uncertain, perhaps derived from Tibetan སྟོད་བོད (stod-bod) meaning "Upper Tibet", itself from the autonym བོད (Bod). Alternately the name may be of Turkic origin, possibly from Old Turkic töbäd meaning "heights" or töpü meaning "peak, height, summit". This is the name of a region and plateau in Inner Asia. It was also the name of an independent state that existed between 1912 and 1951, as well as the name of a present-day autonomous region of China.
