Is there such a thing as compound collective noun?

There's no formal grammatical term like "compound collective noun." However, the concept you're describing definitely exists in the English language!

Let's break it down:

* Collective noun: A word that represents a group of people, animals, or things (e.g., team, flock, herd).

* Compound word: A word made up of two or more words combined (e.g., bookcase, snowflake, sunrise).

Therefore, a compound collective noun would essentially be a collective noun that's formed by combining two or more words.

Here are some examples of what this might look like:

* "Staff meeting": This combines the collective noun "staff" with the noun "meeting."

* "Crowd of people": This combines the collective noun "crowd" with the noun "people."

* "Fleet of ships": This combines the collective noun "fleet" with the noun "ships."

It's important to note that these compound words are often treated as single units grammatically. So, even though they're made up of multiple words, they function as a singular noun in sentences.

For example:

* The staff meeting was productive. (Singular verb "was")

Even though "staff meeting" is made up of two words, it acts as a single unit in this sentence.

While there might not be a specific term for this type of word, the idea of combining words to create collective nouns is definitely a valid concept in English!
