Final answer:
'Broccoli' is a common noun, referencing a general type of vegetable rather than a specific variety or brand name.
Step-by-step explanation:
In classifications of English nouns, 'broccoli' is considered to be a common noun. This is because common nouns refer to individuals, places, or things within the general categories of people, places, and things. For example, terms like 'city', 'dog', and 'broccoli' are all common nouns because they refer to a general type of place, a general type of animal, and a general type of vegetable, respectively. They do not specify a particular city, a particular dog, or a particular kind of broccoli. Contrastingly, proper nouns would be specific names like 'New York City', 'Fido', or 'Romanesco Broccoli'. Abstract nouns reflect concepts or qualities, like 'love' or 'intelligence', which does not apply to 'broccoli'. Finally, collective nouns represent groups of individuals or things, like 'flock' or 'bunch', and once again, 'broccoli' does not fit this categorization.
