Na-adjectives before は


Do na-adjectives need a な before a は?

> もっと きれいなは どうですか。
>
> もっと きれいは どうですか。

Which is correct?

Personally I think な is needed as the sentence is a shorter form of もっと きれいな
ハンドバッグは どうですか。(replace ハンドバッグ with any noun). References say to use な in front
of modified nouns, but nothing about は particles. I have tried Googling for
もっと (na-adj)なは but I am still not sure.




(The question was answered in the comment section; therefore, I will
community-wiki this.)

Neither is, unfortunately.

The correct sentence that is shortest and most natural would be:

> 「もっときれいな **の** はどうですか。」 ("How about a prettier _**one**_?")

This is because you cannot attach a 「は」 to an adjective without nominalizing
the adjective first.

Also correct but somewhat colloquial/slangy would be:

> 「もっときれいな **やつ** はどうですか。」

Not that I recommend that you use 「やつ」 actively, but you will see/hear it
quite often.
