In linguistics, a hyponym is a word or phrase whose semantic range (meaning) is included within that of another word. For example, scarlet, vermilion, carmine, and crimson are all hyponyms of red (their hypernym), which is, in turn, a hyponym of colour. "Hypernymous" is the adjective form of "hypernym".
