ქა რთველი

Has anyone noticed that the word "kartveli" (ქართველი) breaks down into the following morphemes: "ka+rtveli" (ქა+რთველი), where "ka" = "rka" (Kajaia dictionary), which is not only "horn" but also "a bunch of grapes" (that's why it's called "rkatsiteli"), and "rtveli" is "grape harvest season" (Ariane Chanturia).

Just a curiosity.
