The unique way in which an author puts thoughts into words is called his or her

I am pretty sure that the unique way in which an author puts thoughts into words is called Author's Style. Every talented author has its own way of describing things/developing conflicts and so on. Usually you can even determine the author after looking on a few words as a real master can create his own mood.

Hope that helps.

What is the topic of the paragraph? and what section? if you could include the text that would be great! you!
