Sáo Character

It writes the bird sense of sáo. English glosses include blackbird, starling, or myna; other Nôm spellings exist.

The bird word is traced to Proto-Vietic, a reconstructed ancestor language; Pacoh trao also means “myna.” The flute word sáo is linked to Chinese 哨.

Chữ Nôm adapted Chinese characters and parts to write Vietnamese. A scholarly timeline places Proto-Nôm, an early script phase, in the 8th–9th centuries; by the 17th century, elites cited Vietnamese’s changing syllable structure to defend vernacular writing, once dismissed as uncouth.
