kanji 'seal' radical (radical 26)
Refers to the kanji radical 卩 (わりふ), also known as ふしづくり or まげわりふ. Used in character classification and dictionary lookup, not as a standalone word. Cross-referenced with 割符, but 卩 itself is a radical, not the word 割符.

The radical 卩 is also called 'warifu' and is used as an index in kanji dictionaries.
