Vocabulary revisited

Okay, I've worked over the aikido vocabulary a couple of times here and here, but tonight I feel like trying my hand at another treatment of it (more for my entertainment than anything else). There are (at least) two main sets of Japanese terms for aikido ideas - Aikikai and Tomiki. I don't know why Tomiki named things differently than Ueshiba did - but he did and now a large portion of the aiki world has grown up using different terminology. So, here's a comparison to aid in translation of ideas.

Check out this page for the core of aikikai terminology. In the list that follows, the entries start with Aikikai terms followed by Tomiki synonyms and then by English explanations.

• ikkyo - oshitaoshi - pushing the opponent into an armlock on the ground while holding his wrist and elbow.
• nikkyo - kotemawashi - wristlock bending the little finger toward the ulna (armbone).
• sankyo - kotehineri - wristlock with the wrist extended and the forearm turned inward.
• yonkyo - tekubiosae - nerve attack on the forearm or using the forearm to push the opponent away similar to ikkyo/oshitaoshi.
• gokyo - wakigatame - locking the elbow and leading the opponent into unbalance along the length of the arm. Similar in form to ikkyo/oshitaoshi but with a different grip.
• shihonage - shihonage or tenkai kotegaeshi. wrist/arm lock done by holding a wrist with both hands and turning outward and under the arm to twist the arm behind uke's shoulder and head.
• iriminage - shomenate, aigamaeate, gyakugamaeate, or aikinage - any blending evasion followed by a whole-body strike that takes uke off his feet. Gyakugamaeate is also called sokumen iriminage.
• kotegaeshi - kotegaeshi. Wristlock done by flexing the wrist and turning the forearm outward.
• kaitennage - kaitennage or udehineri. Locking the shoulder by holding it behind uke's back and using the arm as a lever to push uke away. Sometimes similar to the hammerlock in common wrestling.
• tenchinage - tenchinage or sumiotoshi or osotogari. Leading the opponent into sideways offbalance with one of his arms held low and the other high. Sometimes it is a hand throw - Aikikai calls this kokyu (breath throw) and Tomiki calls this ukiwaza (floating technique). At other times it is done stepping in behind ukes leg to trip him.
