Some words sit higher in a hierarchy of meaning. A hypernym is a broader term that encompasses more specific words, as vehicle encompasses car, bicycle, and truck.

Hypernymy organizes thesauri and lexical databases such as WordNet. Speakers choose hypernyms when precise identity is unknown or irrelevant, and they choose hyponyms when detail matters. Children gradually refine overly broad labels into more specific vocabulary.

Semantic networks built on hypernym links support artificial intelligence tasks like question answering. In technical writing, moving up or down the hypernym ladder adjusts the level of abstraction for the audience. Clear hierarchical vocabulary helps both human and machine reasoning about categories.

• Broad term including more specific words
• Opposite relation to hyponym
