I think the following words are abstract nouns :

old, new, young.

Is it right?
No, they are adjectives. See [url=http://www.arts.uottawa.ca/writcent/hypergrammar/nouns.html ]NOUNS[/url].
Mister MicawberNo, they are adjectives. See [url=http://www.arts.uottawa.ca/writcent/hypergrammar/nouns.html ]NOUNS[/url].

OK, thanks


Could you tell me the noun forms of the following words :

old, new young.
Students: Are you brave enough to let our tutors analyse your pronunciation?
age, newness, youth
Ok, thank you.
