Linguistics
In Kartvelian languages the principles of creation of the term "Semodgoma" (autumn) proves that from the point of Prakartvelian view the main activity was agriculture. In terms of seasons the main determinate word is "zapxuli" (summer) and this season also is divided into two seasons "gazapxuli" (spring) - the season of beginning the agricultural activities and "stveli"||"rtveli" (vintage) - gathering grapes. This kind of division is similar to the division of seasons in Kheth language.
The terms "muZ„uer" and "Semodegi"||"Semodgoma" (autumn) are created by astronomical knowledges.
