Sino-Tibetan *kolo "Wheel"
by Robert S. Bauer
Introduction
That the horse-drawn chariot appeared suddenly in China in the Shang Dynasty (ca. 1500 -1066 BC) has led some Western scholars to believe that it was not independently invented by the Chinese but was introduced there by Western invaders. This paper is based on the premise that there is a connection between the transmission of the horse-drawn chariot from the West into China and the origin of some words meaning "wheel" and "wheeled-vehicle" in Sino- Tibetan languages. In particular, the paper proposes that words for "wheel" in some northern Chinese dialects and Bodic (Tibetan) languages are ultimately derived from an Indo-European source. On the basis of the comparison of words for "wheel" from various Sinitic and Bodic languages, the author has reconstructed the Proto-Sino-Tibetan root *kolo "wheel" which is itself an Indo-European contact loanword.
