Idiomatic expressions are phrases that have a figurative meaning different from their literal interpretation. For example, saying someone "kicked the bucket" means they died, not that they physically kicked a bucket. These expressions are often unique to a particular language or culture, making them challenging for non-native speakers to understand. These phrases enrich language by adding color and depth to communication. They can convey emotions, humor, or cultural references in a concise way. Common examples include "break the ice" to mean starting a conversation or "spill the beans" to indicate revealing a secret. Understanding idiomatic expressions is essential for effective communication in any language.
