I can’t find it easily enough to excerpt here, but something I found in McCarthy’s Blood Meridian awed me when I first read it since it was the first time I’d come across it. It was a repetition of words in a phrase, and it was just awesome.
I’ve run across it elsewhere since, but have run into two examples in Stories for Late at Night:
Faster and more fast was the beat of music, and Lolita circled faster and yet faster, stamping her right foot sharply…etc. (Pieces of Silver, Brett Halliday, p. 151)
The boy, in his tweed jacket, thick flannel trousers, and over-tight collar, at whose front blazed a tie which hoped to look like that of some famous school or college, was hot, and very hot. (Our Feathered Friends, Philip MacDonald, p. 216)
In the first case above, it suits perfectly, fulfilling its purpose of emphasizing the increasing speed of both the music and Lolita’s dancing. Even the repetition of the repeated adjective doesn’t deflate its impact.
In the second, it seems out of place within both the language and the context of the story. The drama called up by the repeated "hot" doesn’t seem appropriate to being overdressed. While the author included the word "blazed" to describe and place the boy’s tie, I would have assumed that it was colorful, rather than merely looking like a school tie, which to me, would place at either navy or maroon.
So the use of language, the playing with it, is something that can work, or not.
