grapefruit

Definition

The tree of the species Citrus paradisi, a hybrid of Citrus maxima and sweet orange.

Etymology

Widely assumed to be a marketing term from grape + fruit, an allusion to the supposed grapelike clusters of fruit on the tree, early 19th c. Ciardi proposes another theory: one of the pomelo's botanical names is Citrus grandis, meaning "great citrus [fruit]", due to the size of its fruit. A new pomelo variety might first have been called a "greatfruit" (see greatfruit), and through the process of assimilation, the word came to be pronounced "grapefruit".
