would require any other change — to punctuation, word order or any other aspect of the sentence’s grammar. But there’s a world of difference at the semantic level — ‘A or B’ is not two things. (In any given situation, it might be: ‘Are you hungry or thirsty? Both.’ But that’s not inherent in the meaning of or
.) So the choice must be between A and
B: ‘You can choose tea or coffee’ but ‘You can choose between tea and coffee’.
