So, in Aikido we have two main groups of attacks, being grabs or strikes. So, when we're taking a look at some of the basic grabs that we'll deal with, the very first thing that we'll see is katatetori. That's one hand grabbing one hand. So, if I were to offer gyaku-hanmi katatetori. Gyaku literally means the opposite or the backside. So, with my right foot forward, my partner's left foot is forward. So, we are actually opposite. This is gyaku-hanmi katatetori. If we were to change hanmi, so my partner's grabbing with the other hand, this would be ai-hanmi katatetori. The ai is the same ai as in aikido. Which means harmony or the same thing, blending. So, my right foot forward, my partner's right foot is also forward, so we're actually in harmony together. We can also have ryotetori. Which is both hands grabbing both hands. Ryo means both. The te part of the word is literally hand. You'll hear the same in karate. Which means hand. And tori is to grab. And we can also deal with morotetori. Which means both hands, grabbing one. Which will give me a whole new set of movements I have to deal with. But, in terms of the hand grabs, that's the most common series of things you'll see. We also have ushiro ryotetori. Which is behind and grabbing both hands. Again, you hear ryo for both, tetori. So, ushiro, behind. Ryo-te-tori, grabbing from behind, both hands. So, we have gyaku-hanmi katatetori. Ai-hanmi katatetori. We have ryotetori, or both. We have morotetori, both hands on one. We also have ushiro ryotetori. All right. Grabbing both hands from behind. So, these are the series of attacks that you'll see most often in terms of hand grabs.
