Connective

From Glottopedia
Jump to: navigation, search

In semantics, connective is a logical operator which combines with one or more formulas to form a more complex formula.

Examples

Binary connectives, like &, v, -> and <->, combine with two formulas as in (i), the unary connective Neg combines with one formula as in (ii).

(i)

    Phi  &  Psi		(and)
    Phi  v  Psi		(or)
    Phi  -> Psi	(if ... then ...)
    Phi <-> Psi	(... if and only if ...)

(ii)

    Neg Phi		(not)

Comment

The truth-value of the complex formula is always a function (a truth-function) of the truth-values of the formulas Phi and Psi, which can be represented in a truth table.
