Idioms are expressions that have a figurative meaning that is different from the literal meaning of the words. They are often culturally specific and can be difficult for non-native speakers to understand.
For example, the English idiom "kick the bucket" means "to die", while the Spanish idiom "tirar la toalla" means "to give up".
Here are some other terms related to idioms:
* Collocation: A phrase that is commonly used in a particular language, but doesn't necessarily have a figurative meaning.
* Proverb: A short, well-known saying that expresses a common truth or belief.
* Slang: Informal language that is used by a particular group of people.
