The word "or" is a conjunction used to present alternatives or choices between two or more options. For example, when someone asks, "Would you like tea beverage or coffee beverage?" they are giving you a choice between two drinks. In logic and mathematics, "or" can also refer to a logical operation that results in true if at least one of the conditions is true. For instance, in the statement "A or B," the result is true if either A is true, B is true, or both are true.
