Choosing life or lives depends mainly on how many individual existences you mean. Life is normally singular when discussing one person’s existence, a shared existence, or life as a general concept. Lives is the ordinary plural when referring to two or more separate existences.
However, pronouns such as our and their can make the choice less obvious. A plural possessor does not automatically require lives. Meaning determines whether the noun should be singular or plural.
Quick Answer
Use life for one existence, life in general, or a shared way of living. Use lives when referring to two or more separate individual existences. Therefore, both forms can be correct: They changed their lives refers to individual lives, while they built a life together describes one shared existence.

What Is the Difference Between Life or Lives?
The main difference is grammatical number. Life is a singular noun, while lives is its plural noun form. Merriam-Webster lists lives as the plural of life, confirming this basic relationship in standard English (Merriam-Webster).
Compare:
- Maya has a busy life.
- Maya and Elena have busy lives.
- One life was saved.
- Three lives were saved.
However, number is not the whole story. Life can also describe existence or human experience as a general concept: “Life changes quickly.” In that use, you are not counting individual existences.
Life as a Singular Noun and General Concept
Use life when you mean one person’s existence or a single period or way of living. In these cases, it functions as a countable noun.
For example:
- He lived a peaceful life.
- Her life changed after college.
- The accident put one life at risk.
However, life can also express the broad condition or experience of being alive. This use behaves more like an uncountable noun or general concept:
- Life is unpredictable.
- Scientists study life in extreme environments.
- Music brings joy to life.
Therefore, “Life is short” does not mean that only one person’s existence is short. Here, life represents human existence generally.
Lives as a Plural Noun
Use lives when you are counting or discussing the separate existence or experience of multiple people, animals, or other living beings.
For example:
- The new policy affected their lives.
- Firefighters saved several lives.
- The sisters followed very different paths in their lives.
This is the standard plural. Cambridge Dictionary likewise identifies noun lives as the plural of life.
The concept of individual lives is especially useful when choosing between the forms. If each person has a separate existence, experience, history, or lifestyle, the plural is normally the clearer choice.
Why Life Becomes Lives: The Irregular Plural Pattern
The standard irregular plural of life is lives. You do not normally create the plural simply by adding -s.
Compare these related patterns:
- life → lives
- wife → wives
- knife → knives
- leaf → leaves
However, English nouns ending in f or fe do not all follow this pattern. For example, chief becomes chiefs. Consequently, it is safer to learn life → lives as an established form instead of assuming every -f noun behaves alike.
Collins Dictionary also records lives as the plural noun and provides its pronunciation.
Our Life or Our Lives?
Both our life and our lives can be correct, but their meanings differ.
Use our lives when we refers to several people who each have an individual existence:
- Technology has changed our lives.
- We made important choices in our lives.
- Our teachers influenced our lives.
Use the singular when the speakers mean one shared life or a collective experience:
- We started our life together in Chicago.
- Our married life has been peaceful.
- This is the happiest period of our life together.
Therefore, the pronoun our does not automatically require a plural noun. Ask whether you mean separate experiences or one shared experience.
Their Life or Their Lives?
Use their lives when their refers to several people and you mean each person’s separate existence.
For example:
- The students returned to their lives after graduation.
- The experience changed their lives.
- The twins led very different lives.
However, their life can be correct. One important reason is singular they. For example: “Someone may change their life after receiving the opportunity.” Here, their refers to one person, so singular life is logical.
A plural group can also have a collective existence: “The couple described their life together.” Thus, subject-verb agreement does not determine this choice by itself; the intended number of lives matters.
Noun Lives vs. Verb Lives
The spelling lives represents both a noun and a verb, but the pronunciation changes.
As a noun lives, meaning more than one life, it is pronounced /laɪvz/, with the vowel sound in five:
- The rescue saved three lives.
As verb lives, the third-person singular form of live, it is pronounced /lɪvz/, with the vowel in give:
- She lives in Boston.
So, the sentence structure helps identify the part of speech. In “He lives alone,” lives describes what he does. In “He saved lives,” it names the existences that were saved.
Life’s, Lives, and Lifes
These forms should not be treated as interchangeable.
Life’s can be a singular possessive:
- Her life’s purpose became clear.
- That was his life’s greatest achievement.
It can also act as a contraction:
- Life’s too short. = Life is too short.
- Life’s changed. = Life has changed.
Meanwhile, lives is the normal plural of life. Writing lifes for several human or animal lives is incorrect.
There is, however, an important spelling nuance. In the artistic compound still life, the conventional plural is still lifes, not still lives. Merriam-Webster records still lifes as the plural for paintings or photographs featuring inanimate subjects. This exception is one reason to avoid the overly broad claim that the letter sequence lifes can never occur in English.
Common Life or Lives Mistakes
Most errors come from confusing plural spelling or assuming a plural possessor always needs a plural noun.
Incorrect:
“Many lifes were affected.”
Correct:
“Many lives were affected.”
Incorrect in the usual individual sense:
“The employees returned to their normal life.”
Better:
“The employees returned to their normal lives.”
However, do not change every instance automatically. Consider:
“After moving in together, they began a new life.”
Here, singular life works because the sentence describes one new shared way of living.
Likewise, “Everyone should enjoy their life” can be natural because everyone refers grammatically to individual people one at a time.
A Simple Decision Rule
A quick four-part test can resolve most cases.
- One person’s existence? Use life.
“She enjoys her life.” - Several separate existences? Use lives.
“They enjoy their lives.” - Existence as a general idea? Use life.
“Life can change suddenly.” - Several people sharing one way of living? Singular life may be appropriate.
“They built a life together.”
This decision rule is more reliable than looking only at words such as our, their, people, or everyone. First identify what the noun actually represents. Then choose its number.
FAQs
The standard plural of life is lives. For example, write “The doctors saved two lives,” not “two lifes.” The spelling changes from f to v before the plural -s is added.
Yes. Our life is correct when several people describe a shared existence or experience, as in “our life together.” If each person has a separate experience, our lives is usually more natural.
Use their lives for several people’s individual existences: “The program changed their lives.” Use their life when their refers to one person through singular they, or when a group shares one collective way of life.
No. Lives can also be the third-person singular present form of the verb live. In “Daniel lives nearby,” it is a verb. In “The firefighters saved lives,” it is a plural noun.
Plural noun lives is pronounced /laɪvz/, rhyming closely with wives. The verb in “she lives here” is /lɪvz/. Thus, identical spelling can represent two different sounds and grammatical functions.
Lifes is not the ordinary plural of life; use lives for multiple existences. However, lifes legitimately appears inside certain established compound plurals. For example, the art term still life becomes still lifes.
Yes. People’s lives is correct when referring to the individual experiences or existences of multiple people. For example, “Public transportation affects people’s lives.” If you mean human existence collectively, a singular construction such as “human life” may fit better.
Conclusion
The choice between life or lives becomes simple once you identify what is being counted. Use life for one person’s existence, a shared existence, or life as a general concept. Use lives for two or more separate existences or personal experiences.
Remember that plural possessors such as our and their do not automatically require lives. Meaning comes first. Also distinguish plural noun lives from verb lives, and use life’s only when an apostrophe is grammatically required.
