The English language is one of the most difficult languages to learn as a second language. In part, this difficulty is caused by all of the idioms that exist in all aspects of the language. An idiom is a construction of words or a phrase that means something different than what the words are literally saying. Idioms are passed down through tradition, culture, and history. Individuals whose primary language is English are able to understand English idioms. However, those with English as a second language (ESL) will often take idioms to mean literally what they say.

Now that you know what an idiom is by definition, here are some examples of idioms in the English language to further explain this literary term.

How this is used: My mother in law is so crazy; I honestly think that she is one card short of a deck.
