Nôm character for rice

In Vietnamese Nôm, 𥺊 writes words for rice and porridge.

Chữ Nôm is a historical writing system used to write Vietnamese with Chinese-derived and locally made characters. 𥺊 combines a meaning clue and a sound clue: 米 points to rice, while 告 supplies the sound element. Vietnamese Nôm sources record gạo for rice milled before cooking and cháo for rice porridge; another entry uses gạo for the kapok tree.

A Nôm woodblock edition printed in 1774, Tân biên Truyền kỳ mạn lục, uses 𥺊 for gạo in a line about cooking grain for provisions. A Nôm glossary printed in 1898 records cháo for thick rice porridge and points to 𥹙 as another written form. A Chinese dictionary separately gives Southwestern Mandarin, a regional variety of Mandarin Chinese, káo for thick, paste-like food such as rice or corn gruel.
