Is a large restaurants collective noun?

That's a tricky one! It depends on how you're using the word "large" and what exactly you're referring to.

* If you're talking about a group of individual restaurants that are all large in size: Then no, "large" wouldn't be a collective noun. You'd need a different noun to describe the group, like "chain" or "collection."

* If you're talking about a single restaurant that's large and contains many smaller sections or businesses within it: Then "large" wouldn't be a collective noun in this case either. You might describe it as a "complex" or "food hall."

Here are some examples:

* "A chain of large restaurants opened across the city." (Chain is the collective noun, not large.)

* "The large restaurant had several dining areas, a bar, and a bakery." (Large describes the restaurant, not a group of restaurants.)
