Radical 口 · Mouth Radical (mouth, speaking, breath)

Semantic Clue (形旁): 口 (indicates that the action involves the mouth, breath, or voicing sounds)

Phonetic Clue (声旁): 又 (original sound: tan)

A mouth (口) letting out a breath or sound represented by a hand/action shape (又), combining to show someone sighing.

  • 口 Mouth or breath indicator
  • 又 Phonetic and structural component
Liushu category: Phono-semantic (形声)

Origin: Originally formed with a mouth symbol to represent breathing out audibly, later paired with a phonetic element to standardize the sound 'tàn'.

  • In classical literature, sighing often carried deep philosophical weight regarding the transience of life.
