English idioms are a group of words which have a meaning that is not obvious from looking at the individual words. They have developed over time and so they might seem random to you. English idioms often rely on analogies and metaphors.

To understand English as it is spoken in real life, you have to be familiar with idioms. They are used so much in everyday English that it is important to be aware of them. Some might even sound familiar to you from the German language.
