The Chinese word **辫子 (biànzi)**, meaning "braid" or "pigtail," is a compound ideogram formed through semantic combination. Its core component, **辡 (biàn)**, originally depicted two criminals or two parties arguing ("to dispute"), but here it phonetically suggests the sound *biàn* while semantically contributing the idea of "two parts" or "pairing." This is combined with the silk radical **纟 (sī)**, indicating that the object is made of or resembles intertwined threads or strands. Therefore, the character **辫** visually represents the intertwining of two strands of hair or thread into a single braided plait, with **子 (zi)** added as a common nominal suffix to form the everyday word.
