Ơ
# Ơ

Ơ (o con cuerno) es una de las 12 vocales del idioma vietnamita. Se pronuncia [ɤ] (como una [o] no redondeada).

Como ocurre con la mayoría de las letras vietnamitas especiales, esta letra no está bien respaldada por fuentes y, a menudo, se escribe como o+ o como o*. El estándar VIQR es o+.

En el teclado vietnamita predeterminado de Windows, la Ơ se puede encontrar donde estaría la tecla "]" en un teclado en inglés de EE.UU.

Debido a que el vietnamita es un idioma tonal, para marcar los seis tonos posibles esta letra puede tener cualquiera de los cinco superíndices o subíndice.

* Ờ ờ
* Ớ ớ
* Ở ở
