grammar - What are the various ways to express 'or' and when are they appropriate?


I'd like to get an idea of when it is appropriate to use different expressions for expressing disjunction (of the inclusive AND exclusive variety).


「AとBとCの中で...」、「どちら」、and 「か」 come to mind, but I think they have situational usage (that I'm not entirely aware of). 「か」 seems somewhat awkward, 「どちら」 is limited to a decision between two things, and so forth. How would an inclusive or be expressed ('A or B' as opposed to 'either A or B')?



Answer



Natural languages usually have exclusive disjunction. In order to express inclusive disjunction, you usually have to add some materials to exclusive disjunction.




  • Exclusive disjunction between two things




    A か B (の({うち/間}の)どちらか(一つ/一方))
    'between A or B'





  • Exclusive disjunction among more than two things



    A か B, (か) C (の({うち/間/中}の)どれか(一つ))
    'among A, B, or C'






  • Inclusive disjunction between two things



    A か B の({うち/間}の)少なくとも{一つ/一方}
    'A and/or B'





  • Inclusive disjunction among more than two things




    A か B, (か) C の({うち/間/中}の)少なくとも一つ
    'A, B, and/or C'







Since the OP seems to be having trouble with the notation, I will expand the first one so that there is no parentheses and braces:

  • Exclusive disjunction between two things


    A か B
    A か B のどちらか
    A か B のどちらか一つ
    A か B のどちらか一方
    A か B のうちのどちらか
    A か B の間のどちらか
    A か B のうちのどちらか一つ
    A か B のうちのどちらか一方
    A か B の間のどちらか一つ

    A か B の間のどちらか一方
