Suppose I want to use the phrase "many, many" to compound the "maniness" of the thing I'm describing.

> There are **many, many** people.

> The people (of which there are **many, many**)

The first one is standard, but the second one is contended. *Can* it be used in that way?

An example of one that wouldn't be so awkward is:

> There are **lots and lots** of people.

> The people (of which there are **lots and lots**)

Each one can be properly used in its singular form, but once repeated, one of them falls apart. Why?
