Digestive System Idioms

Body Idioms Course Idioms | Vocabulary | English in Use


I am determined to make idioms as accessible for all students as any other part of the English language. Reading and memorising lists of vocabulary is not the most productive, interesting, or useful exercise in English language learning. I created these Activities to encourage you to not only learn and remember many English idioms, but also to have fun with them, as having fun is a great aid to learning and remembering. It is important that you know as many idioms as possible as native English speakers use them with alarming regularity. I hope that as you work your way through the Idiom Activities you will make some of the idioms your own and use them regularly like a native.


Did you know that there are over 600,000 words in English? That's a lot of words, and far more than any human being could ever manage to learn. Even Shakespeare only used around 55,000 different words in all of his works. Mind you, he did actually invent quite a few of them. To get a good mastery of English, you do need to expand your vocabulary as much as possible. The more words you know, the better your English will be. The Activities here will help you to quickly develop your vocabulary.

English in Use

The Activities categorised as English in Use look at the way we use English in everyday life. The Activities cover the actual use of English and examine grammar, punctuation, and functionality of the language. For any student studying English as a second language or English as a foreign language, English in Use Activities are particularly useful for improving speaking, writing, reading, and listening skills. These Activities will help you to develop your confidence in using different types of text such as fiction, newspapers and magazines, as well as learning to speak and write about things such as the weather and travel, as well as preparing you for typical situations such as ordering in a restaurant or buying a train ticket.

Body Idioms

I originally thought that I would find 100 to 200 idioms related to the body, but as I continued gathering the idioms for each part of the body, I realised there were going to be considerably more. With an ever-growing list of idioms before me, I despaired of ever being able to complete the definitions and examples that would be required for each one. However, with a bit of elbow grease, I put my back into it, and managed to complete all 522 of them. In this course, you will find many of the idiomatic expressions related to the body.
