noun
kanji 'fire' radical at bottom (radical 86)
Refers specifically to the 灬 radical when it appears at the bottom of a kanji, as in 点, 熱, or 照. Used in kanji dictionaries and character analysis.
「点」の下の部分は列火と呼ばれる部首です。
The bottom part of '点' is a radical called 列火.
Another name for the same radical (灬), but 列火 is the more common term in many kanji references.
The name 列火 (れっか) literally means 'lined-up fire', describing the appearance of the four dots at the bottom of characters like 点. The origin is uncertain, but it likely arose as a descriptive term in traditional kanji studies.
