What are idioms characterized by?

Idioms are characterized by expressions that carry metaphorical meanings rather than literal interpretations. For instance, phrases like "kick the bucket" or "spill the beans" do not convey their meanings based on the individual words but rather through established cultural usage that conveys a different idea. This metaphorical nature is what distinguishes idioms from straightforward language, where words mean exactly what they say.

Choosing expressions with metaphorical meanings reflects the heart of what makes idioms unique; they often convey concepts, feelings, or actions in a way that isn’t immediately obvious from the words themselves. Understanding idioms enhances comprehension and communication, particularly in contexts where language is rich in figurative speech.
