noun
Refers to a spool or bobbin used for thread or yarn, especially in traditional weaving or sewing contexts. The word is relatively rare in modern everyday language.
祖母は古い綜麻に糸を巻いていた。
My grandmother was winding thread onto an old bobbin.
この織機には小さなへそがいくつか必要だ。
This loom requires several small bobbins.
The origin is uncertain. The kanji spellings 巻子 (literally 'winding child') and 綜麻 (hemp weaving) are likely ateji or conventional associations rather than reflecting a clear historical derivation.
