Are the words " knowledgable and "daring" nouns in the sentence --" readers admire his knowledge and daring

Question

I think readers are nouns but why would knowledge and daring be nouns.

Answer 1

If you write the sentence correctly with capitals and punctuation, the whole thing would be better.

Readers admire his knowledge and daring.

Yes ... in that sentence "knowledge" and "daring" are nouns, along with "Readers."
