What does zea mean?
Zea is chiefly encountered today as the capitalized botanical genus name for a group of tropical American grasses, most familiarly maize, Zea mays. In older English, zea was also a common noun for maize, but that usage is obsolete and normally appears in historical botanical writing. The modern scientific name is useful to readers because it identifies maize within a wider plant group that also includes teosintes and their wild and domesticated relatives. Taxonomists write the genus name with a capital Z, while the species name is lowercase. Although the word may look obscure outside botany and agricultural history, its subject is globally significant: maize is a major staple food, livestock feed, and industrial crop. The historical form also shows how vocabulary shifts, as a name that once referred simply to a familiar grain was standardized as the formal label for the genus containing it.

Etymology of zea
The name comes through New Latin from Ancient Greek zeía, meaning maize or a kind of grain. Linnaeus formally established Zea as a botanical genus in the 18th century, borrowing the Greek name for the maize plant. The same Greek source underlies zein, the name of a protein found in maize.
