aliorelative

Meanings

1. 1
   noun

   in logic, a relation that no term bears to itself; an irreflexive relation

   The relation less than is an aliorelative because no number is less than itself.

2. 2
   adj

   of a relation, holding only between a thing and something other than itself

   Russell calls diversity aliorelative because an object cannot be diverse from itself.

Formed from Latin alius ("other") + relative. Its construction expresses a relation directed toward another thing rather than the same thing; older mathematical logic used it for what is now commonly called an irreflexive relation.
