About
唏 is a phono-semantic compound with the semantic radical 口 (mouth) on the left and the phonetic component 希 (xī) on the right. It primarily denotes the audible expressions of emotional distress, such as sighing, sobbing, or lamenting. Although 希 independently means "hope" or "rare", here it functions solely to provide the pronunciation. This character often appears in compound words like 唏嘘, which describes continuous sighing or sniveling, to convey sorrowful or regretful vocalizations.
