「殳」は部首の一つで、右側に来るとき「るまた」と呼ばれる。
殳 is one of the kanji radicals, and when it appears on the right side it is called るまた.
殳旁 refers to the same radical when it appears on the left side of a kanji, whereas 殳 (るまた) is the right-side form.
The reading るまた is a mnemonic based on the shape: the top part resembles katakana ル (ru) and the bottom part resembles katakana マ (ma) with a 又 (mata) component. The exact origin of this naming convention is uncertain.
