Everyday conversational English is littered with idioms, expressions and reference to proverbs. With ESO you can learn British and American slang expressions, as well as the meanings behind some of the more common English proverbs.
When you come across a saying you don't understand ask the speaker for an explanation, or write it down so you can ask your ESO tutor during your next lesson. If you are planning to use your English in a particular context, for example in a business environment, or on the sports field, your ESO tutor can tailor the lesson to your needs, and include the expressions you are most likely to come across.
