When something is unique, it is one of a kind. When something is one of a kind because it is truly better than the rest, it is nonpareil. The adjective nonpareil means "having no equal; peerless," and it suggests exceptional quality or skill. A nonpareil singer, for instance, is one so proficient, they stand alone in their class. Nonpareil can also be used as a noun to refer to a person or thing having no equal, and, in the plural, to those colorful sprinkles that top various kinds of sweet treats, making them just a little better than the rest.
