The functions of the *s- prefix and the *-s suffix are not clear. Possible explanations include:
 * *s- as a directive prefix and *-s as a nominalizer ;
 * *s- is an iterative prefix, literally "to pass on again" ;
 * *s- (possibly with *-s) as a nominalizer.

Alternatively, it may be derived from a word like (< ), literally "to start the circle/cycle again".

Outside of Sino-Tibetan, this word has been compared to 🇨🇬, which considers to be a loan from Chinese, as well as 🇨🇬.
