About
The character "龊" originates from its traditional form "齪", which combines the "齒" (tooth) radical with the "足" (foot) component, implying an initial meaning associated with actions like biting and trampling. This structure reflected a literal sense of crushing or grinding, but over time the character's independent use declined as it became fixed in the compound "齷齪", where it acquired a metaphorical meaning describing moral or physical filth. The simplified form "龊" replaces "齒" with "齿" while retaining "足", a graphical adjustment that postdates the semantic evolution from concrete action to abstract derogatory term.
