"In logic and mathematics, a two-place logical connective or, is a logical disjunction, also known as inclusive disjunction or alternation, that results in true whenever one or more of its operands are true. E.g. in this context, "A or B" is true if A is true, or if B is true, or if both A and B are true" (Wikipedia)

Examples of logical connectives include "and" (conjunction), "or" (disjunction), "not" (negation), "if...then" (implication), and "if and only if" (biconditional). These connectives are used in logic to combine or modify statements.

The logical connective "or" is called the disjunction of the statements R and S in the statement "R or S."
