The logical operation of formation of the statement "A or B" from two statements $A$ and $B$. In formalized languages the disjunction of two statements $A$ and $B$ is denoted by $A\lor B$. The statements $A$ and $B$ are called the disjunctive terms of the statement $A\lor B$. The meaning of the disjunction can be expressed by the following truth table:

$A$ $B$ $A\lor B$
$T$ $T$ $T$
$T$ $F$ $T$
$F$ $T$ $T$
$F$ $F$ $F$
