An archaic term possibly meaning to vaunt excessively or to show off in a boastful manner.
Possibly from de- (prefix for emphasis or reversal) + vaunt (to boast), from Old French 'vanter.' The exact etymology is uncertain due to the word's extreme rarity.
This word is so rare that it might be a variant spelling or scribal error that got copied repeatedly—it's like finding a typographical ghost in the English language, appearing in old texts but seemingly never used in actual communication!
