Idioms, Terms, and Expressions: A Fun ExplorationWe use all sorts of terms and expressions, but don't really understand the meaning and origin. This book offers a fun exploration of the meaning behind these expressions. Perhaps it was due to a 35+ year career as a medical radiation physicist, but asking "Why?" was common for the author. This simple question was applied to all sorts of idioms, terms or expressions that we speak or hear from others without much regard to what we are actually saying. This book explores the origin of many of these expressions in a light-hearted manner.There rarely is a misunderstanding when we voice or hear "Roger Wilco", "Raining Cats and Dogs", "Caught with Egg on My Face" or other absurd sounding expressions. No one taught us why they work yet we just continue to blindly use them without regard to their background. After reading this book, you will have a better understanding of the meaning and origin or the "Why" behind these colorful expressions, the new knowledge will put you in "7th Heaven" or on "Cloud Nine"!
