hypernyymihyponyyymi

Hypernyymihyponyyymi is a nonce term in lexical semantics used to describe a bidirectional or dual-role hypernymy relation within a single lexical item across different senses or domains. The coinage fuses hypernym, hyponymy, and the -ymi suffix to evoke a recursive, self-referential texture of lexical taxonomy.

In theory, the concept denotes situations where a word functions as a hypernym for some terms in one sense while the same lexeme functions as a hyponym for a broader term in another sense or domain. This typically arises from polysemy, homonymy, or cross-domain terminology, and it is especially relevant in lexical databases and knowledge graphs where sense distinctions matter.

In a simplified representation, a hypernyymihyponyyymi relation can be sketched as a center node connected to hypernymic and hyponymic edges in different sense branches, illustrating the potential for a single word to occupy contrasting hierarchical positions depending on interpretation.

Usage and status: The term is not standard in scholarly linguistics; it appears chiefly in theoretical discussions, thought experiments, or educational glossaries addressing the complexity of lexical hierarchies, polysemy, and multi-domain ontologies.
