‘Or both’: A note on the alleged exclusivity of disjunction in English

Abstract

Abstract I make a point concerning the construction ‘A or B or both’ in English, to the effect that if the connective ‘or’ is understood exclusively across the board then this familiar construction cannot convey the intended inclusive sense of disjunction. If we take ‘or’ inclusively, ‘A or B or both’ has the function of emphasizing that the disjunction is inclusive; taking ‘or’ exclusively, it does nothing.
