Ancient forms: 斆, 斅. The former is constructed from the skeleton of 敎／教 (“to teach”) with the addition of two extra components: 1) a 𦥑 component around the top-left 爻 part, in this case signifying mingling hands (hands-on learning); 2) a 冖 (“cover”) over 子 (“child”), representing the cover of a building or school, i.e. the child learns in a roofed place. Shuowen regards 𦥑 as the phonetic component in the character, which may be true according to some Old Chinese reconstructions such as that of Pan Wuyun's, though probably not others. See 教 for more. The earliest structure may suggest its relationship with 六, with reconstruction *rug.
