Idiom: a group of words that means something different than the individual words it contains As with any language, American English is full of idioms, especially when spoken. Idioms add color and texture to language by creating images that convey meanings beyond those of the individual words that make them up. Idioms are culturally bound, providing insight into the history, culture, and outlook of their users. This is because most idioms have developed over time from practices, beliefs, and other aspects of different cultures. As a culture changes, the words used to describe it also change: some idioms fall out of use and others develop to replace them. With idioms in particular, the beliefs or practices leading to their use may disappear while the idiom itself continues to be used. Idioms can be so overused that they become clichés; or they can become slang or jargon, expressions used mainly by specific groups or professions.Idioms can be complimentary or insulting. They can express a wide range of emotions from excitement to depression, love to hate, heroism to cowardice, and anything in between. Idioms are also used to express a sense of time, place, or size. The range of uses for idioms is complex and widespread.The complexity of idioms is what makes them so difficult for non-native speakers to learn. However, this complexity is also what can make idioms so interesting to study and learn; they are rarely boring. Learning about idioms, in this case those used in the United States, provides a way to learn not only the language, but a little about the people who use it.In the Loop is a collection of common idioms updated and compiled from two previous books of idioms published by the Office of English Language Programs: Illustrated American Idioms by Dean Curry and Something to Crow About by Shelley Vance Laflin. In the Loop combines the popular aspects of the previous books, while also updating the content by including idioms that have come into use more recently and eliminating those that are rarely used. When available, background information is included about the origins of the idioms. Additionally, In the Loop includes categories of commonly used idioms and suggestions to the teacher to aid in developing classroom exercises for learning the meanings and uses of idioms. In essence, this book is intended to be both a teaching tool and a reference.
