Sometimes people feel cut off from others. They may feel left out, lonely, or distant. This is called isolation. It can happen when someone moves to a new place, stays home for a long time, or feels different from those around them. Writers and speakers often use idioms to talk about this feeling in a more interesting way.
Idioms are phrases that don’t mean exactly what the words say. For example, saying “on an island” doesn’t mean someone is really on an island. It means they feel alone. In this article, you’ll learn some common idioms people use to describe isolation. Each idiom comes with a meaning and an example to help you understand it clearly.
