Reconstruction:Proto-Koreanic/Pwutukye

Etymology
Ultimately from.

The first two syllables must certainly reflect or a similar Chinese form for "Buddha". Thomas Pellard connects the final syllable to, a common element in the noble titles of the and  kingdoms of ancient Korea, and to , appearing in  with the apparent meaning of "king". Pellard thus hypothesizes that the Korean word originally meant "Lord Buddha" or "King Buddha".

Reconstruction notes
The reconstruction is supported primarily by the Manchu and Japanese borrowings; comparative reconstruction within Koreanic only goes back to Middle Korean. However, the exact consonantal match between Jurchenic and Japanese cannot be explained historically without positing a Koreanic source.

To explain the differences in vowel quality between the three languages, Pellard notes that Old Korean very possibly lacked vowel harmony (which is in fact never written in Old Korean orthography), and that Middle Korean may derive from Old Korean. Therefore, the word reconstructed in as  may actually have had the phonetic value, which matches Old Japanese  quite well.

While universally agreed to be a Koreanic borrowing, the Manchu form is in fact more problematic than Pellard supposes. Pellard believes that Jurchen would have borrowed as  because Manchu  has the phonetic value, but this is really the result of a Manchu sound shift from ; thirteenth-century Jin Jurchen did in fact have. In all likelihood, the Koreanic donor to Jurchenic, probably the speech of 🇨🇬, had a different vocalism from the 🇨🇬 donor to Japan or the 🇨🇬 ancestor of Middle Korean.

The Japanese and Korean etymologies have traditional Chinese-based etymologies, but both are less likely than the Koreanic explanation.
