Etymologies
For the etymology of tian, Schuessler (2007:495) links it with the Mongolian word tengri "sky, heaven, heavenly deity" or the Tibeto-Burman words taleŋ (Adi) and tǎ-lyaŋ (Lepcha), both meaning "sky". Schuessler (2007:211) also suggests a likely connection between Chinese tiān 天, diān 巔 "summit, mountaintop", and diān 顛 "summit, top of the head, forehead", which have cognates such as Naga tiŋ "sky".
