Word Origin & History. empty O.E. Ã¦mettig at leisure, not occupied, unmarried, from Ã¦metta leisure, from Ã¦ not + -metta, from motan to have (see might). The -p- is a euphonic insertion. Sense evolution from at leisure to empty is paralleled in several languages, cf. The adj. adeios must have been applied first to persons who enjoyed freedom from duties, leisure, and so were unoccupied, whence it was extended to objects that were unoccupied [Buck].
Karate, as we know it, is not one word but rather two separate kanji that denote Empty and Hand. Kara and Te are combined to mean Empty Hand, and thus it was born. It is important to note that in true Karate study one does not study the use of weapons and that is a common misconception. Weapons training is called Kobudo and is a separate art from Karate...but both origionate in Okinawa.
