Hypernymy and hyponymy are the semantic relations between a generic term (hypernym) and a more specific term (hyponym). The hypernym is also called a supertype, umbrella term, or blanket term. The hyponym names a subtype of the hypernym. The semantic field of the hyponym is included within that of the hypernym. For example, "pigeon", "crow", and "hen" are all hyponyms of "bird" and "animal"; "bird" and "animal" are both hypernyms of "pigeon", "crow", and "hen".
