What word is a synonym for quaint?
odd, special, unusual
Since "queer" and "odd" are synonyms themselves, they could both be used in the place of "quaint." The word suggests a status or a custom that is unusual either because it is from a strange place or from an earlier time. Other synonyms could include bizarre, eccentric, offbeat, oddball, outlandish, peculiar, unconventional, or unusual.
A synonym of a synonym is an alternate word for one of the original word's synonyms: A synonym for "abundance" is "plenty." In that sentence the word "abundance" is the original, and "plenty" is the synonym. It follows that a synonym of the synonym is one of the synonyms for the word, "plenty;" for example, "copiousness."
