And now, Words and Their Stories, from VOA Learning English. Today we talk about an expression, or idiom, involving an animal – a monkey to be exact. Monkeys are intelligent animals, and they often do funny things. So, the English language has some monkey expressions that describe a fun situation. For example, to monkey around means to do things that are not useful or serious. And if something is more fun than a barrel of monkeys , it is very fun! But what if you had to carry a monkey around with you every minute of every day ... on your back? That may not be so fun. And that brings us to today’s expression – to have a monkey on your back . If you have a monkey on your back , you have a problem that cannot be easily solved. And you possibly have had that problem for a long time. To have a monkey on your back can also mean to carry a great emotional weight. This weight comes from a bad decision or perhaps a feeling that you have done something wrong. But the expression is used in more situations than that. It is often used to describe a serious problem, worry, or concern that makes life difficult or unpleasant. Sometimes we use this idiom to describe a situation that is not our fault . It could be a hardship or condition from which we suffer. Here are some examples. A man grew up in extreme poverty. For a time, it was a monkey on his back . But getting a good education was the first step to getting the monkey off his back . If a woman has a gambling, alcohol, or drug addiction , we could say she has a monkey on her back . It could last for many years or even a lifetime. However, if she could solve or end the problem, we could say she finally got the monkey off her back ! There is another expression that also means having a monkey on your back. That expression is a millstone around someone’s neck . A millstone is a very large, heavy stone used for grinding things such as grain or corn. It crushes things easily. So, we also use the word millstone to describe a serious responsibility, problem, or concern. For example, student debt is a millstone for many young people. We could also say the debt is a millstone around their necks or a monkey on their backs . And that’s all the time we have for this Words and Their Stories! Until next time … I’m Anna Matteo.
