adj.
  1. Being the only one of its kind: the unique existing example of Donne's handwriting.
  2. Without an equal or equivalent; unparalleled.
    1. Characteristic of a particular category, condition, or locality: a problem unique to coastal areas.
    2. Informal. Unusual; extraordinary: spoke with a unique accent.

[French, from Old French, from Latin ūnicus.]

uniquely u·nique'ly adv.

USAGE NOTE   For many grammarians, unique is the paradigmatic absolute term, a shibboleth that distinguishes between those who understand that such a term cannot be modified by an adverb of degree or a comparative adverb and those who do not. These grammarians would say that a thing is either unique or not unique and that it is therefore incorrect to say that something is very unique or more unique than something else. Most of the Usage Panel supports this traditional view. Eighty percent disapprove of the sentence Her designs are quite unique in today's fashions. But as the language of advertising in particular attests, unique is widely used as a synonym for "worthy of being considered in a class by itself, extraordinary," and if so construed it may arguably be modified. In fact, unique appears as a modified adjective in the work of many reputable writers. A travel writer states that "Chicago is no less unique an American city than New York or San Francisco," for example, and the critic Fredric Jameson writes "The great modern writers have all been defined by the invention or production of rather unique styles." Although these examples of the qualification of unique are defensible, writers should be aware that such constructions are liable to incur the censure of some readers. See Usage Notes at absolute, equal, infinite.

Wikipedia: Uniqueness quantification
Top

In mathematics and logic, the phrase "there is one and only one" is used to indicate that exactly one object with a certain property exists. In mathematical logic, this sort of quantification is known as uniqueness quantification or unique existential quantification.

Uniqueness quantification is often denoted with the symbols "∃!" or ∃=1". For example, the formal statement

\exists! n \in \mathbb{N}\,(n - 2 = 4)

may be read aloud as "there is exactly one natural number n such that n - 2 = 4".

Reduction to ordinary existential and universal quantification

Uniqueness quantification can be expressed in terms of the existential and universal quantifiers of predicate logic by defining the formula ∃!x P(x) to mean

\exists x\,(P(x) \wedge \forall y\,(P(y) \to x = y)).

An equivalent definition that has the virtue of separating the notions of existence and uniqueness into two clauses, at the expense of brevity, is

\exists x\,P(x) \wedge \forall y\, \forall z\,((P(y) \And P(z)) \to y = z).

Another equivalent definition with the advantage of brevity is

\exists x\,\forall y\,(x = y \leftrightarrow P(y)).

Generalizations

One generalization of uniqueness quantification is counting quantification. This includes both quantification of the form "exactly k objects exist such that …" as well as "infinitely many objects exist such that …" and "only finitely many object exist such that…". The first of these forms is expressible using ordinary quantifiers, but the latter two cannot be expressed in ordinary first-order logic.
