This book goes into much detail of the slang, sayings and dialect in Ireland, IF you are solely interested in the northern part of the country. The author obviously did their research in Ulster and sadly neglected the largest area of the island. In localizing his search to this small area they have made shortchanged their readers. They neglected to take anything from places like Dublin, Cork, Kerry, Limerick, all places with a wealth of slang all of their own. As well as these places, they omitted the more general slang that is used across the country as a whole. My wife and I were sadly disappointed with this badly put together, badly researched, badly localized waste of paper!
