Relative Term
A relative term is a term that makes two or more distinct references to objects (which may be the same object, for example in "The Morning Star is the Evening Star"). A relative term is typically expressed in ordinary language by means of a phrase with explicit or implicit blanks. Examples: * ''__ loves'' * ''__ is the same object as __'' * ''__ is giver of __ to __''. The word is is a relative term when it expresses identity. The colloquial meaning for a relative term is that it is different for different people or situations. An example: someone who is 5 feet tall might think someone who is 5 feet six inches tall is tall, but someone who is 6 feet would think that that person is short. An atom is big compared to a quark, but it is very small when compared to a body cell. Fast food may be healthier than preserved food, but unhealthy compared to organic produce.

Theory Of Relations
In mathematics, a finitary relation over sets is a subset of the Cartesian product ; that is, it is a set of ''n''-tuples consisting of elements ''x''''i'' in ''X''''i''. Typically, the relation describes a possible connection between the elements of an ''n''-tuple. For example, the relation "''x'' is divisible by ''y'' and ''z''" consists of the set of 3-tuples such that when substituted to ''x'', ''y'' and ''z'', respectively, make the sentence true. The non-negative integer ''n'' giving the number of "places" in the relation is called the '' arity'', ''adicity'' or ''degree'' of the relation. A relation with ''n'' "places" is variously called an ''n''-ary relation, an ''n''-adic relation or a relation of degree ''n''. Relations with a finite number of places are called ''finitary relations'' (or simply ''relations'' if the context is clear). It is also possible to generalize the concept to ''infinitary relations'' with infinite sequences. An ''n''-ary relation over sets i ...
