The word "or" is a conjunction used to present alternatives or choices between two or more options. It helps clarify that one option can be selected instead of another. For example, in the sentence "Would you like tea beverage or coffee beverage?" the use of "or" indicates that the person can choose one of the 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. This is often represented as "A or B" where if either A or B is true, the overall statement is true.
