7.2 Hyponymy

Hyponymy is an inclusive relationship where some lexemes are co-hyponyms of another that includes them. As cutlery includes knife, fork, spoon (but not teacup) these are co-hyponyms of the parent or superordinating term. This traditional term denotes a grouping similar to a semantic field. So cod, guppy, salmon and trout are hyponyms for fish, while fleet has the hyponyms battleship, aircraft carrier, cruiser, destroyer and frigate.
