Translation:Tomatoes, cabbages, carrots, and pumpkins are vegetables.
vegetable [vej-tuh-buh l, vej-i-tuh-] noun
- any plant whose fruit, seeds, roots, tubers, bulbs, stems, leaves, or flower parts are used as food, as the tomato, bean, beet, potato, onion, asparagus, spinach, or cauliflower.
- the edible part of such a plant, as the tuber of the potato.
- any member of the vegetable kingdom; plant.
I think that definition makes it pretty clear that any fruit can be considered a vegetable, unless you insist on applying the strictest definition of the word. The least strict definitions suggest that all plants are vegetables.
