			For example, a theory ''T'' of arithmetic is said to be inconsistent if there exists a proof in ''T'' of the formula "0=1". The formula I(''T''), which says that ''T'' is inconsistent, is thus an existential formula. A witness for the inconsistency of ''T'' is a particular proof of "0 = 1" in ''T''.

			Boolos, Burgess, and Jeffrey (2002:81) define the notion of a witness with the example, in which ''S'' is an ''n''-place relation on natural numbers, ''R'' is an ''n''-place [[computable set\|recursive relation]], and ↔ indicates [[logical equivalence]] (if and only if):
			::" ''S''(''x''<sub>1</sub>, ..., ''x''<sub>''n''</sub>) ↔ ∃''y'' ''R''(''x''<sub>1</sub>, . . ., ''x''<sub>''n''</sub>, ''y'')
			:" A ''y'' such that ''R'' holds of the ''x<sub>i</sub>'' may be called a 'witness' to the relation ''S'' holding of the ''x<sub>i</sub>'' (provided we understand that when the witness is a number rather than a person, a witness only testifies to what is true)." In this particular example, B-B-J have defined ''s'' to be ''(positively) recursively semidecidable'', or simply ''semirecursive''.

			== Henkin witnesses ==

			In [[predicate calculus]], a '''Henkin witness''' for a sentence <math>\exists x\, \phi(x)</math> in a theory ''T'' is a [[term (logic)\|term]] ''c'' such that ''T'' proves φ(''c'') (Hinman 2005:196). The use of such witnesses is a key technique in the proof of [[Gödel's completeness theorem]] presented by [[Leon Henkin]] in 1949.

			== Relation to game semantics ==

			The notion of witness leads to the more general idea of [[game semantics]]. In the case of sentence <math>\exists x\, \phi(x)</math> the winning strategy for the verifier is to pick a witness for <math>\phi</math>. For more complex formulas involving [[universal quantifier]]s, the existence of a winning strategy for the verifier depends on the existence of appropriate [[Skolem function]]s. For example, if ''S'' denotes <math>\forall x \exists y\, \phi(x,y)</math> then an [[equisatisfiable]] statement for ''S'' is <math>\exists f \forall x \, \phi(x,f(x))</math>. The Skolem function ''f'' (if it exists) actually codifies a winning strategy for the verifier of ''S'' by returning a witness for the existential sub-formula for every choice of ''x'' the falsifier might make.
