Benedict Arnold

Obviously, Benedict Arnold is a person’s name, but it is also used as an idiom. An idiom is a word, group of words or phrase that has a figurative meaning that is not easily deduced from its literal definition. Often using descriptive imagery, common idioms are words and phrases used in the English language in order to convey a concise idea, and are often spoken or are considered informal or conversational. English idioms can illustrate emotion more quickly than a phrase that has a literal meaning, even when the etymology or origin of the idiomatic expression is lost. An idiom is a metaphorical figure of speech, and it is understood that it is not a use of literal language. Figures of speech have definitions and connotations that go beyond the literal meaning of the words. Mastery of the turn of phrase of an idiom or other parts of speech is essential for the English learner. Many English as a Second Language students do not understand idiomatic expressions that native speakers understand such as in a blue moon, spill the beans, let the cat out of the bag, chin up, eye to eye, barking up the wrong tree, hit the nail on the head, kicked the bucket, blow off steam, piece of cake, hit the sack, and raining cats and dogs, as they attempt to translate them word for word, which yields only the literal meaning. In addition to learning vocabulary and grammar, one must understand the phrasing of the figurative language of idiomatic phrases in order to know English like a native speaker. We will examine the meaning of the idiom Benedict Arnold, where it came from, and some examples of its use in sentences

A Benedict Arnold is a traitor, someone who has been revered or been elevated to a place of trust and has betrayed that trust. The idiom Benedict Arnold is an American term and has been in use since shortly after the Revolutionary War. The idiom Benedict Arnold is derived from a very real person who was a general for the Americans during the Revolutionary War. Benedict Arnold was born in the Connecticut Colony in 1741 and fought in the French and Indian War for a very brief period when still in his teens. He became a successful apothecary, continuing to conduct business in defiance of the Sugar Act and the Stamp Act. He joined the fight for independence against Britain and King George III as a captain in the militia, taking part in the siege of Boston that occurred after the Battles of Lexington and Concord and helping Ethan Allen and the Green Mountain Boys to capture Fort Ticonderoga and Fort Saint-Jean. He went on to attack Quebec and take part in the Saratoga campaign. He was promoted to major general, but still felt that he did not receive the recognition that he deserved. When serving as military governor of Philadelphia, he was accused of misusing his office. Eventually, debt-ridden and bitter, he spied for Britain and agreed to turn over the fort at West Point to the British for twenty thousand pounds, a fortune by today’s standards. Unfortunately for Arnold, the plot was uncovered and he was forced to flee. Though Arnold was guilty of treason, he was never brought to justice. The idiom Benedict Arnold, which has been in use since at least 1806, is still a stinging accusation in American English. Note that both words are capitalized, as it is a proper name.
