A hypernym is a linguistic term for a word whose meaning includes the meanings of other words, as the meaning of transportation includes the meaning of train, chariot, dogsled[?], airplane, and automobile.
Hypernym is the opposite of hyponym, a word whose meaning is included by another.
A word is a hypernym (in Greek υπερνύμιον, literally meaning 'extra name') if its meaning encompasses the meaning of another word of which it is a hypernym; a word that is more generic or broad than another given word.
