Which part of speech is sunny-side up?

Dictionaries present it as an adjective, but I think it can be used as a noun too.

The interesting part is that this adjective is introduced as a post modifier and cannot be used before nouns.

I would be grateful if you could express your opinion about this issue.


I like my eggs sunny-side up.

I don't like scrambled eggs. My favourite is sunny-side side up.


Can you suggest a sentence in which this would be a noun?

Hi Clive.

I like sunny-side ups.

I don't like scrambled eggs; sunny side ups are my favorites.

Aren't the above sentences correct?

Thanks for your time and help

I've never heard that said, or read it.

You can certainly use adjectives as nouns,

eg heal the sick, arrest the accused

but it's a matter of usage, Some will sound OK and some will sound odd.

This sounds odd.

Thanks Clive for your explanation.

Yes, the use of the before some adjectives make them noun.

Would you rewrite my examples in a natural way?
