@Troy El Bey Taekwon Sahyunim. The fundamental movement Twigi (jumping) terminology has only 2 purposes by the Generals definition in the encyclopedia. 1. To cover a protracted distance *in a single motion! Without gathering 2.To evade a low swinging attack (sword, pole, bat etc) ITF encyclopedia Vol IV pg 314. In its definition any attack or defense performed after the “Twigi” is separate from the action and technique of jumping. If someone (forbid) swung a baseball bat at my legs. The action of me evading the attack by jumping (Twigi) is separate from the counter attack I choose to execute after the initial jump performed in a single motion and landed. In volumes 3 and 4 all of our Hand and foot Technique are defined. There is not a single account where General Choi defined hand or foot technique as Twigi. You will see Twimyo (flying) Twio Nono (overhead) Twio Dolmyo (mid air) Twimyo Soogi (flying hand techniques etc. please correct me if I am incorrect b.u.t you will NOT see Twigi ap cha busigi, or Twigi sonkal taerigi etc. The movement of Twigi is a separate technique and falls into the category Bang Eau Gi (defensive techniques with the feet) including dodging, foot shifting, stepping, sliding, turning, body dropping , and foot lifting. Twimyo is the over arching umbrella of attacking techniques while in the air and subdivided into mid air, overhead, etc. The confusion may be that we are leaving the ground in a jumping motion to execute the above mentioned techniques. That should not be confused with the actual technique of jumping (Twigi) defined by General Choi Willing this makes sense Taekwon Sabum N Fernandez
