Is broadness the abstract noun for broad?

No, "broadness" is not the abstract noun for "broad". While it's a related word, it doesn't directly represent the abstract concept of being broad.

Here's why:

* "Broad" is an adjective, describing a quality of something (e.g., a broad street, broad shoulders).

* "Broadness" is also a noun, but it refers specifically to the extent or scope of something, often in terms of width or range.

A more accurate abstract noun for "broad" would be "breadth."

Here's an example:

* Adjective: The river has a broad channel.

* Abstract Noun: The breadth of the river is impressive.

"Breadth" captures the abstract quality of being broad, while "broadness" focuses on the specific quality of being wide or extensive.
