What is An Idiom? An Ultimate Overview

Are you also looking for the simplest answer about what is an idiom and its different types, along with examples? This is one of the most important questions students and professionals find difficult to understand. Daily, we all hear lectures, attend seminars and conferences, and see movies where teachers, mentors or actors use idioms in their conversations.

In addition to this, being a student or researcher, you also have to use idiomatic terms, phrases or expressions in your thesis, essay, presentations or assignments. But we often cram and use them wherever we want without understanding their true structure, definitions and meanings.

In this blog, we will take practical examples to understand the use of different types and categories of idioms. Moreover, we will explore the characteristics of idiomatic expressions and discuss their differences with metaphors and phrases.

We have also crafted an extensive list of idioms personalized for students, kids and academic research writing. So, without much ado, let’s straightaway jump into it.

Idiom Definition – A Beginner’s Friendly Quick Guide

The word Idiom is derived from the Greek word idios, which means ‘private .’It is a common phrase, expression, or saying whose meaning you can’t derive from looking at the individual words.

These figurative terms have non-literal meanings; we can’t understand them only by deciphering the words.

For example, when someone says, “It’s raining cats and dogs, ” it does not illustrate that the cats and dogs are falling from the sky. Instead, it means that “it’s raining heavily.”

Similarly, the idiom “don’t beat about the bush” has a different meaning when broken down into individual words. However, its idiomatic meaning is “Don’t talk about irrelevant and unimportant things; just come to the point.”

The idiom “That’s how the ball bounces” seemingly means ” how balls jump.”. But in idiomatic terms, its correct meaning is that “the things are just out of our control.” 

Similarly, when we say “kill two birds with one stone,” we never mean to kill the birds using the stone. We mean to say that “complete two tasks at once.”

To understand more clearly, let’s break them down into simpler steps.

  • Expression or Word Combination:
    • An idiom can be a phrase, expression, or combination of words.
    •  It can be even a single word that can act as idiomatically.
  • Peculiar:
    • These are commonly used in a special community or group of people familiar with them, such as native or fluent speakers.
    • It is similar to a joke or any funny terms we discuss in our private friend’s group, etc., and no one can literally understand them.
    • Every language has some private language terms that are strange to others.
    •  In a nutshell, these are rare to understand for everybody.
  • Figurative Meaning: To understand it, consider any language has two layers such as:
    • Literal Meaning: Words, expressions, or phrases that we can simply and straightaway search in the dictionary to understand. For example, “Cow has four legs.”
    • Figurative Meaning: Figurative terms or words are those that we can’t understand in a non-literal way. These don’t have straightaway meanings and definitions.
  • Different from Literal Meaning:
    • We can’t derive or understand their meanings by looking at the individual word in an idiomatic expression.
    • For example, “that is the way ball bounces” is an idiom, but we can derive its meanings correctly by looking individual words up in a dictionary.

Types of Idioms with Meaning, Sentences and Examples

4 Common Types of Idioms

There are four types of idioms such as (1) Pure Idiom, (2) Binomial Idiom, (3) Partial Idiom, and (4) Prepositional Idiom.

Let us understand them one by one.

Pure Idiom:

  • Pure idioms are typical idioms that we use regularly. This means, in the normal way, when people think or talk about idioms, they refer to these kinds of idioms.
  • In these phrases or expressions, the individual word or component does not contain any relationship or resemblance with the actual meaning of the phrase.
  • This means we can’t deduce or understand them by looking at the individual words.
  • Seemingly, they don’t have any literal meanings.
  • They are private, and only the native people or the groups of people can understand them easily.
  • In a nutshell, pure idioms are non-transparent idioms where an individual word or component provides no literal meaning or hint.

Pure Idiom Meaning and Example Sentences:

Binomial Idiom:

  • The binomial idioms contain exactly two words.
  • These are joined or connected using a conjunction or any preposition.
  • They work as a single idiomatic unit or expression to convey meaning.
  • You can’t break them into individual parts or words to understand them correctly.

Binomial Idioms Meaning and Example Sentences:

“Night and day”“Shows the difference between two things.”You have improved your performance like night and day compared to the previous month. 

Partial Idiom:

  • Partial idioms are those idiomatic phrases or expressions that are not complete on their own.
  • They are sometimes called clipped idioms because they contain only a partial or single part of the original idioms.
  • They usually borrow the first part of the first few words from the original idiomatic sentences.
  • Although they don’t contain the full structure, they keep the figurative or original meaning intact.
  • Native speakers or people familiar with these terms readily understand the meaning and context without worrying about the missing part or structure.
  • For example, “spill the bean” is a partial idiom, while its full form is “spill the bean about something.”
  • Moreover, “kick the bucket” is a partial idiom, while its complete version is “kick the bucket like a horse.”

Partial Idiom Meaning and Examples:

Prepositional Idiom

  • Prepositional idioms are those expressions or phrases in which the meaning of the entire Idiom depends upon the preposition.
  • This means that changing the preposition alters the context of the entire idiomatic phrase.
  • Prepositional idioms contain prepositions such as “in,” on,” “under,” etc.
  • They contain prepositions along with nouns, verbs, and adjectives.
