嗾 is not used independently in modern Chinese; it survives mainly in the literary compound 嗾使 (to instigate, to put someone up to something). It pairs the mouth radical 口 with the phonetic 族, picturing the hissing sound made to urge a dog to attack.

Archaic and literary only; seen in old texts and etymology notes, not in everyday speech. The classical line 公嗾夫獒焉 (the duke sicced that mastiff on him) appears in the Zuo Zhuan.
