Relative term

A relative term, also called a rhema or a rheme, is a logical term that requires reference to any number of other objects, called the correlates of the term, in order to denote a definite object, called the relate (pronounced with the accent on the first syllable) of the relative term in question. A relative term is typically expressed in ordinary language by means of a phrase with explicit or implicit blanks, for example, lover of __, or giver of __ to __.
