armlock
A martial arts technique that hyperextends or twists the opponent's arm to control or submit them. Common in judo, jujutsu, and mixed martial arts.
He applied an armlock in the match and made his opponent tap out.
In judo, the cross armlock (ude-hishigi-juji-gatame) is often used.
Common spelling in martial arts contexts; uses hiragana for the second part to avoid rare kanji.
Alternate spelling using 挫 (sprain, crush); less common but seen in some martial arts texts.
Compound of 腕 (ude, 'arm') and ひしぎ (hishigi), the nominalized form of ひしぐ (hishigu, 'to crush or sprain'). The spelling 挫ぎ uses the kanji 挫 (sprain, crush).
