vegetable

When referring to food, "vegetable" can be used as a countable noun (e.g., "one vegetable") or as an uncountable collective noun when talking about the food group in general (e.g., "Eat more vegetable"). The use of this word to describe a person who cannot move or speak is very informal and is considered offensive or insensitive. It should be avoided in professional or medical contexts. In common speech, people often use "vegetables" as a general category, even though some plants we call vegetables (like tomatoes) are botanically fruits.
