1. Having an old-fashioned attractiveness or charm; oddly picturesque: "They saw a quaint old house during their travels."
2. Strange, peculiar; or unusual in an interesting, pleasing, or amusing way: "He was known to have a quaint sense of humor."
3. Unfamiliar or unusual in character; strange.
4. Skillfully or cleverly made; artful.
5. Obsolete: wise; skilled.
6. Etymology: from about 1225, "cunning, proud, ingenious", from Old French cointe, "pretty, clever, knowing"; from Latin cognitus, "known"; past participle of cognoscere "to get or to come to know well".

The sense of "old-fashioned but charming" is first attested to about 1795, and could describe the word itself, which had become rare after about 1700; although it soon recovered popularity in this secondary sense.
