5. Etymology: "living and growing as a plant", from Old French "living, fit to live", from Medieval Latin vegetabilis, "growing, flourishing", from Late Latin vegertabilis, "animating, enlivening", from Latin vegertare, "to enliven", from vegetus, "vigorous, active", form vegere, "to be alive, to be active, to quicken".

In 1582, it was recorded for the first time that the adjective use of vegetable became familiar to English, "having to do with plants".

In a work of the same date appears the first instance of vegetable as a noun, meaning "a plant".

It was not until the 18th century that the noun and adjective were used more restrictively to refer specifically to certain kinds of plants that are eaten.
