Question

How convinced the writing is <= possible to use this phase as noun?

Answer 1

&quot;how convinced the writing is&quot; is not grammatical. using it as a noun would not be grammatical.

you can say: &quot;how convincing the writing is&quot; but you need to finish the thought. that is an incomplete sentence, just a clause.

a full sentence would be:

&quot;How convincing the writing is depends upon the style and supporting sentences for the argument.&quot;

as far as using something like that as a noun, you could try it as an adjective and a noun:

&quot;The convincing writing caused the newspaper editor to shout &quot;Stop the presses!&quot;
