e/Section headers of a Chinese dictionary

Information
has gloss	eng: Section headers (in Chinese, 部首 bùshǒu), also known as index keys or classifiers, are graphic portions of Chinese characters which are used for organizing entries in Chinese dictionaries in sections which all share the same graphic part. In practice the most common term for these is radical; however, this term has been used in many different ways, leading to great confusion, as explained at Radical (Chinese character). For disambiguation purposes, the term radical is thus avoided here.
lexicalization	eng: Section headers of a Chinese dictionary
instance of	(noun) letters or symbols that are written or imprinted on a surface to represent the sounds or words of a language; "he turned the paper over so the writing wouldn't show"; "the doctor's writing was illegible" writing
