This book is a fascinating continuation of the journey begun by researcher St. Clair in 2010 and contained in the original volume of Most Comprehensive Origins of Cliches, Proverbs and Figurative Expressions published in 2013, and revised in 2014 and 2015. As in that work, like his previous phrase origin books, St. Clair disproves much folk etymology and claims by other published sources, often by showing earlier citations which indicate that many popular stories regarding the origins of idioms, proverbs and metaphors are totally untrue.Some new features include cross-referencing on expressions which may be arranged in more than one way, plus referrals back to the original volume when applicable. Also he has added numerical identification of those entries primarily native to Britain and Australia. Another new aspect is inclusion of some common oxymorons which have become cliche. This volume had over 1,000 new entries in its original release and is a must for those who own the first volume.Then, in August, 2019, this volume was completely revised and expanded. Over 170 new expressions were added, and a few duplicates were removed. The Index Book was also brought up to date.
