Dictionary Definition

“a figure in speech in which a word or phrase literally denoting one kind of object or idea is used in place of another to suggest a likeness or analogy between them (as in drowning in money)” [1]

“an expression, often found in literature, that describes a person or object by referring to something that is considered to have similar characteristics to that person or object:
“The mind is an ocean” and “the city is a jungle” are both metaphors.
Metaphor and simile are the most commonly used figures of speech in everyday language.” [2]

Different Types of Metaphors

There are many types of metaphors in English. Some are used in everyday speech, others appear more often in literature, poems, or advertising. Here are six common types:

Standard Metaphors

A standard metaphor makes a direct comparison between two things. It says that one thing is another to show a strong image or feeling.

  • The classroom was a zoo.
    (This means the classroom was loud and out of control, not that it was really a zoo.)

Implied Metaphors

An implied metaphor doesn’t say one thing is another, but suggests the comparison indirectly.

  • She barked instructions at her team.
    (It suggests she acted like a dog, without saying “She is a dog.”)

Mixed Metaphors

A mixed metaphor combines two different metaphors, which can sometimes be confusing or funny.

  • We’ll burn that bridge when we get to it.
    (This mixes two expressions: “burning bridges” and “cross that bridge when we come to it.”)

Visual Metaphors

A visual metaphor uses an image or design to show a comparison. These are often found in advertising or film.

  • A car ad shows a car with wings to suggest speed and freedom.
    (The image compares the car to a bird without using words.)

Extended Metaphors

An extended metaphor is a longer comparison that continues through several lines or sentences. Writers often use these in stories or poems.

  • Life is a journey with many stops, detours, and unexpected turns.
    (This idea continues and builds the image of life as a journey.)

Dead Metaphors

A dead metaphor is a metaphor people use so often that they forget it’s a metaphor. The image is no longer strong or surprising.

  • Time is running out.
    (We don’t picture time with legs, but we still understand the meaning.)

2 -Difference Between Metaphors and Similes and Analogies

Simile and Metaphors are both figures of speech that use a comparison of two things but they have differences.

  1. Metaphors do not use ‘as’ and ‘like’ to make the comparison
  2. Metaphors make a direct comparison, whilst similes make an indirect comparison
  3. Metaphors can be used over a larger text, whereas similes are generally very short phrase or small sentences.

An analogy explains how two things are alike in more detail.

metaphors vs other expressions

Metaphors compare ideas in a creative way. Unlike idioms or proverbs, metaphors are not fixed phrases and often appear in poems, songs, and everyday speech.

3 - How to Use Metaphors

Metaphors are commonly used in everyday speech, literature, and even in professional settings. They help to create imagery and convey complex ideas in a more relatable way. When using metaphors:

  • Choose comparisons that are clear and relatable to your audience
  • Don’t overuse them – a few well-placed metaphors are more effective than too many
  • Be aware of cultural differences, as some metaphors may not translate well across cultures

To create a metaphor, think of two things that share a quality, and say one is the other — like “My mind is a sponge” to show you learn quickly.

You can use a metaphor in writing or speaking to make ideas stronger or more interesting — for example, “He’s a rock in tough times.”

4 - Examples of Metaphors

To understand metaphors and how they are used here are four examples with definitions, example sentences and conversation and an explanation of their use

Time is a thief

Definition: This metaphor suggests that time steals moments from our lives.

Example Sentences:

  • “As we grow older, we realize that time is a thief.”
  •  “Cherish every moment, because time is a thief that takes away our youth.”

Example Conversation:

  • Person 1: “I can’t believe how fast this year has gone by.”
  • Person 2: “I know! Time is such a thief, isn’t it?”
  • Person 1: “Yeah, it really sneaks up on you.”

Explanation: This metaphor expresses the idea that time can take away valuable experiences or moments in life. The term thief is used to describe someone that wrongly takes away your belonging, therefore if time is a thief it is stealing valuable time away from you.

Life is a journey

Definition: This metaphor describes life as an adventure filled with various experiences.

Example Sentences:

  • “Remember, life is a journey, not a destination.”
  • “Each setback is just a detour on this journey we call life.”

Example Conversation:

  • Person 1: “I’m feeling lost after college.”
  • Person 2:  “Don’t worry! Life is a journey, and you’ll find your way.”

Explanation: This metaphor emphasizes the idea that life consists of experiences and lessons learned along the way. We think of a journey as an adventure of traveling and experiences and therefore we have experiences while we travel through our life.

The world is a stage

Definition: This metaphor suggests that life is like a play where everyone has roles to play.

Example Sentences:

  • “In this city, it often feels like the world is a stage, and everyone is performing.”
  • “She entered the room like she was stepping onto a stage; the world is a stage, after all.”

Example Conversation:

  • Person 1: “Why do you think everyone acts differently in public?”
  • Person 2: “Because the world is a stage, and people play their parts.”

Explanation: This metaphor conveys the idea that life is a performance, and we each have roles in it. A stage is the place that shows and performances takes place where actors and actresses play roles in a story. This suggests life is like this story with all of us performing a role in this story.

A heart of stone

 Definition: This metaphor indicates that a person is cold to others and lacks emotion.

Example Sentences:

  • “Even after all that happened, he showed he has a heart of stone.”
  • “She’s tough and doesn’t let anyone in; she has a heart of stone.”

Example Conversation:

  • Person 1: “Did you see how he reacted to her tears?”
  • Person 2: “I know, right? He has a heart of stone.”

Explanation: This metaphor highlights a person’s lack of emotional detachment or inability to show compassion. A stone is hard and cold which are terms used when a person is not kind and friendly. So when a person lacks compassion then it is said to be ‘cold’ and that they are ‘hard’.

7 - Metaphor Q & A

What is the definition of a metaphor?
A metaphor is a figure of speech that makes an implied comparison between two unlike things by saying that one thing is another thing. It describes something by comparing it to something else, even though the comparison isn’t literally true. For example, saying “My heart is a rock” suggests emotional hardness — not that your heart is literally made of stone.

What’s the difference between a metaphor and a simile?
A simile makes a comparison using the words “like” or “as” (e.g., “He’s as fast as lightning”), while a metaphor makes a direct comparison without those words (e.g., “He is lightning on the track”). So if a simile compares, a metaphor declares.

Where are metaphors used?
Metaphors are used in literature, song lyrics, advertising, and everyday speech to create vivid imagery or simplify complex ideas. Writers like Emily Dickinson and Shakespeare famously used metaphors to stir emotion and paint memorable images. The phrase “The world’s a stage” is one of the most well-known metaphors in English.

Do metaphors help understanding?
Yes, metaphors help readers or listeners by making difficult ideas easier to understand. They create strong mental pictures that stick in the reader’s mind, especially when describing objects or ideas with similar characteristics.

Can metaphors be negative?
Absolutely. For example, “He has a heart of stone” or “She’s a snake” use metaphors to describe negative traits. A metaphor can reveal admiration (“heart of gold”) or distrust depending on the comparison made.

Is it possible to overuse metaphors?
Yes — using too many metaphors or mixing two unrelated metaphors can confuse readers. Keep your imagery clear and consistent to avoid distraction.

Are metaphors used only in English?
No. Most languages use metaphors, though the specific comparisons often reflect cultural differences. Teaching metaphors to students in their native language can also encourage your child to explore figurative meaning in English.

Useful Information About Metaphors

Metaphors are a literary device that help you say something is something else in a creative way. For example, “Her voice is music to my ears” makes a direct comparison between a voice and music.

A metaphor works by replacing one object or idea with another that shares similar characteristics. It’s not literally true, but it brings your point across with powerful imagery.

Here are some famous examples of metaphors in literature and life:

  • “The world’s a stage” (Shakespeare)
  • “He has a heart of gold”
  • “Time is a thief”
  • “My heart is a battlefield” (Emily Dickinson-like phrasing)
  • “Ideas are fragile eggs”

These metaphors often combine two unrelated things — like time and theft — but they help us understand the literal meaning by creating a mental shortcut.

Metaphors work best when they:

  • Are based on strong imagery or shared understanding
  • Avoid mixing two unrelated metaphors
  • Are not overused
  • Can be extended across several lines (in poetry or essays)

Using direct metaphors like “He’s a rock” makes writing feel bold. Metaphors without “like” or “as” are often more memorable and poetic than similes.
