- It is a spicy(adj) hot(adj) dish(n).
- It is a personal(adj( private(adj) business(n).
- It is a bright(adj) red(adj) car(n).
In the above examples, it looks as if an adjective modifies another adjective.
Can an adjective modify another adjective?
I think not. But an intensifier can. In your examples the adjectives, though more than one in number, qualify the nouns, viz. dish, business and car.
The dish is spicy; the dish is hot > The dish is spicy and hot (It is a spicy and hot dish).
Anglophile,
Can I say it as coordinate adjectives.
“It is a spicy, hot dish.”
The adjectives are separated with comma.
Yes, you may call them so.
