Language is more than just words — it’s full of color, creativity, and culture. One of the best examples of this is idioms. An idiom is a phrase or expression whose meaning is not exactly the same as the literal meaning of its words.
For example, when someone says “break the ice,” they don’t mean smashing frozen water — they mean starting a conversation. Idioms make English more expressive, natural, and fun to use.
When it comes to emotions, especially feeling nervous or anxious, English has dozens of idioms that capture these experiences in unique ways.
Learning idioms for nervousness not only helps you speak like a native but also lets you express emotions more vividly in daily conversations, writing, and even professional settings.
Whether you want to describe exam stress, job interview jitters, or stage fright, these idioms will come in handy.
