Etymology
From, from ; cognate with 🇨🇬, 🇨🇬, 🇨🇬, 🇨🇬, 🇨🇬, 🇨🇬.

The Vietnamese words for "day" and "night" (and their cognates) have the same distribution within Vietic: reflexes of and  are only attested in Thổ, Pong and Viet-Muong, i.e. the "innovative Vietic" group, lacking cognates in the generally more conservative languages.


 * The upper register tone in Thổ Cuối Chăm - ŋaj¹ (A1) - shows that there probably was a presyllable with voiceless initial: if the presyllable had been voiced or if this word had been monosyllabic with a nasal onset, the expected tone would have been A2.
 * The tone of the Vietnamese word is (A2), showing that the presyllable was already lost by the Common Viet-Muong stage, before tones started to develop.

The presence of a presyllable, although it can not be explicitly identified as *t- by Vietic evidence alone, is indicated with a dash in the  reconstruction. This presyllable corresponds to the *t- in other Austroasiatic languages (or some other sound in Northern Austroasiatic in this case: see for examples).

All in all, the relationship between 🇨🇬 and other Austroasiatic words is secure.
