    BJJ glossary: the words to know before your first class

    Brazilian Jiu-Jitsu has its own vocabulary, borrowed from English, Portuguese and Japanese. In your first class you might hear that someone passed your guard, took your back and finished with a choke, and wonder what just happened. You do not need to learn any of this before you start, but knowing the core terms makes everything easier to follow. Here are the words you will hear most.

    Training and the room

    • Gi. The heavy cotton uniform worn in traditional BJJ, with a jacket, trousers and belt. Its collar and sleeves can be gripped.
    • No-gi. Training in shorts and a rash guard, without grips on clothing. Faster and more scrambly. See our gi vs no-gi guide.
    • Rolling. Live sparring, where both partners try to apply what they know against full resistance.
    • Drilling. Repeating a technique with a cooperative partner until it becomes natural.
    • Positional sparring. Live rounds that start from a set position, such as one person in guard, with a specific goal.
    • Open mat. A less structured session to drill, roll or work on your own game.
    • Oss. A greeting and acknowledgement used in many clubs, meaning roughly yes, understood or respect.

    Positions

    • Guard. You are on your back with your legs between you and your partner. It is a position to attack from, not just defend. Closed guard has your legs locked around their waist, open guard does not, and half guard traps one of their legs.
    • Mount. Sitting on top of your partner's torso. One of the strongest positions in BJJ.
    • Side control. Lying across your partner from the side, chest to chest, past their legs.
    • Back control. Behind your partner with your legs hooked in around their hips. Often considered the most dominant position.
    • Base and posture. How stable and upright you are. Good base stops you being swept, good posture stops you being pulled down.

    Movements

    • Shrimp, or hip escape. Moving your hips away from your partner on your side to create space. The most important movement in BJJ.
    • Bridge. Lifting your hips explosively from your back to unbalance someone on top of you.
    • Sweep. Reversing the position from guard so you end up on top.
    • Guard pass. Getting past your partner's legs to reach side control or mount.
    • Takedown. Bringing a standing partner to the ground. Borrowed largely from judo and wrestling.

    Submissions

    • Submission. A choke or joint lock that makes your partner tap.
    • Tap. Tapping your partner or the mat, or saying tap, to signal that you give up. Your partner releases straight away. Tapping is how everyone learns safely.
    • Armbar. Straightening the arm against the elbow joint.
    • Triangle. A choke using your legs around your partner's neck and one arm.
    • Rear naked choke. A choke from back control using the arms, without the gi.
    • Kimura. A shoulder lock that rotates the arm behind the back.

    Belts and progress

    Adult belts go from white to blue, purple, brown and black, and each belt has up to four stripes that mark progress between belts. Promotions take time, and that is part of the appeal. Our article on the BJJ belt system explains how it works.

    You will pick it up fast

    Nobody expects you to know any of this on day one. Coaches explain as they teach, and after a few weeks the vocabulary becomes second nature. At SOL, classes are taught in French and English, and the 6-week Beginners Programme introduces the positions and movements step by step.
