Lives vs Lifes, Which Is Right?

The difference between lives vs lifes might seem minor, but it’s an important one. Lives is a versatile word while lifes isn’t a word in standard English.

Additionally, think of how a classic show like Friends explores the unique lives of its characters. These examples show why getting this right matters, not just for grammar, but for the meaning behind the words. Let’s untangle the rules with Arvin AI’s free Grammar Checker so you never confuse them again.

What Does Lives Mean?

The word lives has two distinct uses in English. And yes, you’ve probably heard or seen it countless times in pop culture.

“Lives” As a Noun:

Lives is the plural form of the word life and refers to multiple existences, beings, or individual stories. If you’ve ever watched Spider-Man, you know his motto: “With great power comes great responsibility.” That’s because Peter Parker is always saving lives while trying to balance his own.

Example: “Superheroes dedicate their efforts to saving lives, often at the expense of their own personal happiness.”

Here, lives refers to multiple people whose existence is at stake.

“Lives” As a Verb:

Lives is also the third-person singular form of the verb live, which means to exist, reside, or simply be alive. Think of how Gotham lives in Bruce Wayne’s memories as both a home and a source of pain.

Example: “Bruce Wayne lives in Gotham, a city constantly in need of saving.”

Examples of Lives in a Sentence

As a Noun:

1. “Doctors in Grey’s Anatomy are constantly trying to save lives in the most dramatic ways possible.”
2. “The characters in Game of Thrones lived dangerous lives, where survival was never guaranteed.”

As a Verb:

1. “Monica lives for hosting Thanksgiving dinners on Friends, even when chaos ensues.”
2. “Wakanda lives on as a symbol of hope and innovation in the Black Panther universe.”

Figurative Usage:

1. “The Marvel Cinematic Universe explores the lives of heroes like Iron Man, who juggle saving the world and their personal struggles.”
2. “In The Sims, players create the lives of virtual people and control every detail, from their jobs to their relationships.”

What Does Lifes Mean?

Lifes is not a proper word in standard English.

While it might seem like the logical plural form of “life,” the correct plural is actually lives. This is because “life” is an irregular noun, and English loves to surprise us with its quirky grammar rules (but you can use this cheat code for grammar!).

Why Lifes Feels Like It Should Be Correct

It feels natural to add an “s” to make most words plural, like “dog” to “dogs” or “car” to “cars.” So, many people mistakenly think the plural of “life” should be lifes.

However, English doesn’t play by the rules when it comes to irregular nouns like “life.”

Why Lifes is Incorrect: Lives vs Lifes

Irregular Plural Rule:

Instead of adding an “s” or “es” to form the plural, the word life changes to lives.

• Example:
  • Incorrect: “The lifes of endangered species need protection.”
  • Correct: “The lives of endangered species need protection.”

Context Doesn’t Save It:

Even in creative writing or informal speech, lifes isn’t acceptable unless you’re deliberately breaking grammar rules for stylistic effect. (And even then, it’s risky because it looks like a typo!)

The Verb/Plural Confusion:

Some mix-ups occur because “lives” is also the third-person singular form of the verb “live” (e.g., “She lives in New York”). However, lifes doesn’t work as either a plural noun or a verb in any context.

Examples of Lifes (Incorrect) in a Sentence vs Lives (Correct)

Incorrect: “Their lifes were full of adventure and excitement.”
Correct: “Their lives were full of adventure and excitement.”

Incorrect: “The lifes of animals are precious.”
Correct: “The lives of animals are precious.”

Key Differences Between Lives vs Lifes

1. Lives Is a Real Word; Lifes Is Not

First things first: lives is both a plural noun and a verb, which makes it pretty versatile.

On the other hand, lifes doesn’t exist in standard English. People might accidentally use it because they assume “life” follows the same plural rules as most words—but it doesn’t. English loves its exceptions, and “life” is one of them.

Aspect	Lives	Lifes
Is it a real word?	Yes, correct in English.	No, it’s not a word in standard English.
Grammatical Function	Plural noun (multiple life stories or beings). Verb (third-person singular of “live”).	Doesn’t have any grammatical function—often mistakenly used as a plural of “life.”
Examples as a Noun	“The doctors saved many lives today.” “This book explores the lives of three friends.”	Incorrect: “The lifes of endangered species need protection.”
Examples as a Verb	“She lives in New York.” “The legend of the hero lives on in our hearts.”	Incorrect: “The story lifes on through generations.”
When to Use	Use lives when talking about: – Multiple existences (plural of life). – Actions (as a verb)	Never use lifes—it is incorrect.
Examples	The Sims lets you create virtual lives. Grey’s Anatomy is all about saving lives.	Might appear stylistically in rare cases (e.g., “Lifes Remaining: 3” in a game).
Mnemonic to Remember	“Cats have nine lives.”	“Lifes” feels logical, but it’s always wrong—just remember, “Life becomes lives.”

Understanding Lives: Uses In The Real World

The word lives is more than a part of language; it’s a reflection of real people and their experiences. From politics to social justice and global events, lives often become the focal point of actions, decisions, and policies.

Lives in Politics: Policies That Shape People’s Futures

During debates about healthcare reform, the phrase “saving lives” is central.

For example, the Affordable Care Act (ACA) in the United States was promoted as a way to protect the lives of over 20 million Americans by providing access to affordable medical care.

Lives in Climate Change: Protecting the Planet’s Future

The climate crisis is another area where activists and world leaders emphasize how global warming threatens not just ecosystems, but the very lives of people worldwide.

Hurricanes, floods, and wildfires fueled by climate change have taken thousands of lives and displaced millions. For example, Hurricane Katrina in 2005 claimed over 1,800 lives, highlighting the importance of disaster preparedness.

Why Lifes is Incorrect

I know it feels like “lifes” should work, especially since we add “s” to make most words plural, like “dog” to “dogs” or “book” to “books.” But nope—lifes isn’t a word. Here’s why, and why it’s important to get it right.

Life is an Irregular Noun

English has irregular nouns—words that don’t follow the standard rules when they become plural. “Life” is one of them. Instead of just tacking on an “s,” it transforms into lives. Think of it like how “child” turns into “children” or “tooth” becomes “teeth.” It’s frustrating at first, but you get used to it.

• Example:
  • Incorrect: “The lifes of the villagers were peaceful.”
  • Correct: “The lives of the villagers were peaceful.”

Even if you’re unsure about the grammar, you’ve definitely heard the word lives used in movies, music, or news. When Beyoncé sings “Who runs the world? Girls!” she’s talking about empowering women and improving their lives, not their “lifes.

Additionally, the Sims tagline is “Play with life.” But if you’re talking about the characters’ multiple stories, you’d say, “The lives of my Sims are chaotic,” not “the lifes.”

So when you’re talking about more than one existence, it’s always lives.

Common Grammar Pitfalls

When it comes to words like lives and lifes, grammar can feel like a trap waiting to catch you. These terms may seem similar, but they have completely different (and sometimes confusing) rules.

1. Using “Lifes” Instead of “Lives”

The Mistake:

People sometimes write “lifes” as the plural of “life,” assuming it follows the standard rule of adding “s” to form a plural.

Why It’s Wrong:

“Life” is an irregular noun. Its plural form is lives, not “lifes.” English has a way of throwing curveballs, and this is one of them.

How to Fix It:

Whenever you’re talking about multiple existences, beings, or experiences, use lives instead of “lifes.”

• Incorrect: “The lifes of these animals are in danger.”
• Correct: “The lives of these animals are in danger.”

2. Confusing Lives (Noun) and Lives (Verb)

The Mistake:

People mix up the two uses of lives—as a plural noun and as the third-person singular form of the verb live.

Why It’s Wrong:

Context is key. As a noun, lives refers to multiple “life” stories or beings. As a verb, it describes an action, like existing or residing.

How to Fix It:

Pay attention to the sentence structure and subject. If it describes what someone does, lives is the verb. If it refers to multiple existences, it’s the noun.

• Noun Example: “The rescue mission saved their lives.”
• Verb Example: “She lives in Paris and enjoys the art scene.”

3. Forgetting the Singular Form

The Mistake:

People sometimes forget to switch back to the singular form, life, when referring to just one existence.

Why It’s Wrong:

The singular and plural forms can’t be swapped out. Life refers to a single person, experience, or existence, while lives means more than one.

How to Fix It:

When in doubt, ask yourself: Am I talking about one person, creature, or experience? If yes, use life.

• Incorrect: “Her lives is filled with adventure.”
• Correct: “Her life is filled with adventure.”

4. Misplacing Lives in Idioms

The Mistake:

Some idiomatic expressions are tied to singular or plural forms of “life,” but people accidentally switch them.

How to Fix It:

Familiarize yourself with these common phrases:

• “The time of your life” (singular).
• “Cats have nine lives” (plural).
• “Risking their lives” (plural).
• Incorrect: “I’m having the time of my lives!”
• Correct: “I’m having the time of my life!”

5. Overusing “Lives” in Figurative Speech

The Mistake:

Sometimes, people use lives in a metaphorical sense where it doesn’t quite fit. For instance, describing inanimate objects as having “lives” when it’s unnecessary.

Why It’s Wrong:

Not everything has a “life” or “lives.” Reserve the word for meaningful contexts, like people, animals, or metaphors with depth.

How to Fix It:

Ask: Does this really relate to existence or survival? If not, rephrase the sentence.

• Incorrect: “This old laptop has lived so many lives.”
• Correct: “This old laptop has been through so much.”

Quick Tips to Avoid Grammar Pitfalls

1. Remember the Rule for Plurals:

Words ending in “fe” or “f” often change to “ves” in the plural
(e.g., life → lives, knife → knives).

2. Practice with Sentences:

Test yourself: “She lives in the city” vs. “Their lives were forever changed.” Which is the noun? Which is the verb?

3. Use Context Clues:

If it’s describing what someone does, it’s the verb. If it’s about multiple people or stories, it’s the noun.

4. Watch Out for Irregular Nouns:

Don’t assume adding “s” works for every word. Learn exceptions like life → lives, wife → wives, or leaf → leaves.

Ditch the dictionary explanation and leave it all up to the grammar checker (from Arvin Ai) to help you proofread and improve your writing.

Common Grammar Pitfalls: Lives vs Lifes

Mistake	Why It’s Wrong	How to Fix It	Examples
Using “Lifes” Instead of “Lives”	“Life” is an irregular noun, so its plural is lives, not “lifes.”	Always use lives when talking about multiple existences, beings, or stories.	Incorrect: “The lifes of animals matter.” Correct: “The lives of animals matter.”
Confusing Lives (Noun) and Lives (Verb)	People mix up the noun lives (plural of life) with the verb lives (to exist or reside).	Check the sentence context—if it’s an action, it’s the verb; if it’s about multiple beings, it’s the noun.	Noun: “The doctors saved their lives.” Verb: “She lives in New York.”
Forgetting the Singular Form “Life”	“Life” (singular) and lives (plural) cannot be used interchangeably.	Use life when referring to one person, being, or experience.	Incorrect: “Her lives is interesting.” Correct: “Her life is interesting.”
Misplacing Lives in Idioms	Idiomatic expressions have fixed forms that don’t change between singular and plural contexts.	Use the correct form for each idiom: life for singular and lives for plural.	Incorrect: “I’m having the time of my lives!” Correct: “I’m having the time of my life!”
Overusing “Lives” in Figurative Speech	Not everything has “lives.” Using it for inanimate objects or concepts can feel unnatural or forced.	Reserve lives for meaningful contexts like people, animals, or impactful metaphors.	Incorrect: “This laptop has lived many lives.” Correct: “This laptop has been through a lot.”

Why Is Lives Both Plural and a Verb?

Lives as the Plural of “Life”

First off, lives is the plural of the noun life. So, when you’re talking about more than one existence, you use lives.

• Think about a headline: “Doctors Save Thousands of Lives in Natural Disaster.”

It’s clear they’re talking about multiple people being saved.

As a Verb (To Live)

Here’s where it gets a little tricky. Lives is also the third-person singular form of the verb live. This means it’s used when talking about what one person, animal, or thing does—like where they reside or how they exist.

• “She lives in New York and spends her weekends volunteering.”

The word lives here isn’t about multiple beings; it’s about one person existing in a specific way.

Lives vs Lifes: What Reddit Would Say?

If you’ve ever wondered about lives vs lifes, just imagine the chaos if someone posted this question on Reddit. You’d have a mix of helpful grammar nerds, sarcastic comments, and maybe someone throwing in a meme for good measure. But here’s the deal: lifes is not a word. It doesn’t belong in proper English. The plural of “life” is always lives.

Use Case	Lifes (Wrong)	Lives (Correct)
Talking about more than one life	“The lifes of cats are fascinating.”	“The lives of cats are fascinating.”
In storytelling	“The novel follows the lifes of three women.”	“The novel follows the lives of three women.”
Headlines or news	“Doctors save many lifes every day.”	“Doctors save many lives every day.”

Lives vs Lifes Examples

• “The doctors saved many lives after the accident.”
• “The novel explores the lives of three different families.”
• “Superheroes dedicate their lives to protecting others.”

Lifes is never correct in this context.

Lives (Verb): Talking About Existence

• “She lives in New York and works as a teacher.”
• “The memory of their friendship still lives on in her heart.”
• “The legend of King Arthur lives through the stories we tell.”

Again, lifes doesn’t work here.

Common Phrases with “Lives”

You’ll often see lives in expressions about survival, stories, or resilience:

• “Cats have nine lives.”
• “Their lives were changed forever after the hurricane.”
• “The soldier sacrificed his life to save others’ lives.”

Lifes isn’t used in any of these cases.

Summary of Examples

Context	Correct: Lives	Incorrect: Lifes
Talking about multiple beings	“The book tells the stories of their lives.”	“The book tells the stories of their lifes.”
Action/verb form	“She lives in Chicago.”	“She lifes in Chicago.”
Phrases/expressions	“Their lives were forever changed.”	“Their lifes were forever changed.”

People’s Life’s or Lives?

Let’s clear this up: each person has one life, but when you’re talking about more than one person, those individual lives become plural—lives. So, it’s always people’s lives, not life’s.

Lives vs Lifes: Grammar Rules

Lives (Verb Form)

When lives is used as a verb, it refers to the act of living, existing, or thriving. It’s the third-person singular form of the verb live (he, she, it).

Life’s (Possessive or Contraction)

Life’s is the possessive form of life or a contraction of life is. It’s never used as a plural.

  (Here, life’s shows possession, meaning the joys that belong to life.)
• “Life’s too short to hold grudges.”
  (Here, life’s = life is.)

Lifes (Incorrect)

“Lifes” is not a word in English.

Differences in Lives vs Lifes: Grammar Rules

Incorrect	Why It’s Wrong	Correct

“Her life’s are full of stories.”	Mixing singular possessive with a plural form.	“The lives of teachers are inspiring.”

Whether it’s used to describe the multiple lives touched by a healthcare worker, the fictional lives in a book like The Great Gatsby, or how a legacy lives on, this word is rich in meaning. Lifes, meanwhile, doesn’t belong in proper English. By choosing lives, you not only stay grammatically accurate, but you also honor the depth and complexity the word represents in our stories, culture, the collective human experience.
