KARA
Indo-European word "kara" denotes a "punishment" and in general "war" or an "army" (like Lithuanian "karas").
The Celts were famous for their chariots and modern English words like "car", "carriage" and "carry" are ultimately derived from the native Brythonic language (Modern Welsh "cerbyd"). The word chariot itself is derived from the Norman French "charriote" and shares a Celtic root (Gaulish "karros"). All this denotes to the etymology of a car meaning simply "the vehicle of war".
In Norse mythology there was a Valkyrie named Kara.
