Suppose I want to enumerate several relations between apple and other kinds of fruit, say pear, orange, and peach. Of course, I can say something like:
(1) relation between apple and pear, relation between apple and orange, relation between apple and peach.
But this sounds too verbose. If I instead say something like
(2) relations between apple and pear, orange and peach,
it becomes less clear what relations I am talking about, in particular, the principal relatum apple common to all three relations does not stand out. Is it better to say something like
(3) relations between apple and pear, and orange, and peach?
(4) relations between apple, pear, orange and peach?
