mediacy definition
mediacy of semantics, by contrast, means that the same principles do not apply. Take the example of ‘sibling’, ‘brother’ and ‘sister’ (in the basic ‘family-relation’ senses in all cases). Let us take it that the delological form / denotation of ‘sibling’ exactly properly includes those of both ‘brother’ and ‘sister’. By analogy with the situation in phonology and its realisations, this would lead us to say that ‘sibling’ corresponds to (has) two contrasting senses – i.e. relates to two delological forms / denotations: 1. ‘brother’; and 2. ‘sister’. This, however, is not right: ‘sibling’ does not correspond to two contrasting senses. Rather it cor- responds to a single sense, covering the full range of both ‘brother’ and ‘sister’. Thus in delology, unlike in phonology, there are cases (in fact many cases) in which one delological form/entity / denotation properly includes another.
