John Gardner, in his wonderful book "The Art of Fiction" uses a word that had me playing word detective. The word is "oonch". (By the way, if you are in the mood for inflicting some serious damage on your gentle, creative self, I would strongly recommend reading this book.)
When I first read it, I could not help but associate it with the Hindi word "oonch", a word meaning "up" or "high" ("oonchai": meaning altitude or height; also, "oonch" + "chai" = "high tea", har har. Just kidding.)
This is how Gardner uses the word:
"Leave nothing--no slightest detail--unexamined; and when you discover implications in some image or event, oonch those implications toward the surface."Unable to find any references in my beloved OED and on the Web, I turned to books.google.com and that paid off.
The Dictionary of American Regional English defines "oonch" as:

So there you go. "Oonch". It's a bit like "oomph" minus the sex appeal.
Here's a really good interview with John Gardner. (Link to Paris Review, pdf of the full interview available in the story.)
