either; neither; Disjunctive determiners mark a noun phrase as definite. They also imply a single selection from a set of exactly two. [1]: 387 Because they signal a single selection, disjunctive determiners select singular nouns when functioning as determinatives in noun phrases (e.g., either side).
In Boolean logic, logical NOR, [1] non-disjunction, or joint denial [1] is a truth-functional operator which produces a result that is the negation of logical or.That is, a sentence of the form (p NOR q) is true precisely when neither p nor q is true—i.e. when both p and q are false.

Either Socrates is mortal, or it is not the case that Socrates is mortal. is true by virtue of its form alone.

The corresponding logical symbols are "", "", [6] and , [10] and sometimes "iff".These are usually treated as equivalent. However, some texts of mathematical logic (particularly those on first-order logic, rather than propositional logic) make a distinction between these, in which the first, ↔, is used as a symbol in logic formulas, while ⇔ is used in reasoning about those logic formulas ...
