I have come across the word "skrewt" and have done a search on the web. From what I can see, it is a made-up word that refers to some monster or other, as found in the Harry Potter books. Since I do not read that kind of material, I was not aware that the creatures were so common. http://www.wordnik.com/words/skrewt Is the word used in any other context? Has it become mainstream yet? Does it refer to a specific kind of creature? Is the word based on an existing word/creature/monster or merely a creation? Insight into skrewts will be welcome.
