\begin{definition}[Definition:Logical Connective]
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.
In mathematics, '''logical connectives''' are considered to be '''truth-functional'''. 
That is, the truth value of a compound statement formed using the '''connective''' is assumed to depend ''only'' on the truth value of the comprising statements.
Thus, as far as the '''connective''' is concerned, it does not matter what the comprising statements precisely ''are''.
As a consequence of this truth-functionality, a '''connective''' has a corresponding truth function, which goes by the same name as the '''connective''' itself.
The arity of this truth function is the number of statements the '''logical connective''' combines into a single compound statement.
