Definition:Logical Connective

Definition
A logical connective is an object which either modifies a statement, or combines existing statements into a new statement, called a compound statement.

It is almost universal to identify a logical connective with the symbol representing it.

Thus, logical connective may also, particularly in symbolic logic, be used to refer to that symbol, rather than speaking of a connective symbol separately.

A connective can be considered as being an operator and, in correspondence therewith, is considered to have an arity.

This arity is the number of statements the logical connective combines into a single compound statement.
