Many English learners and even native speakers get confused about lives and lifes. At first glance, both words seem like they could be correct. After all, many English words become plural by adding -s at the end.
For example:
- Book → Books
- Car → Cars
- House → Houses
Because of this pattern, some people think life becomes lifes in the plural form.
However, English has some irregular plural nouns, and life is one of them. This is why many people are unsure which word to use.
The good news is that the rule is simple once you learn it.
Quick Answer
- ✅ Lives is the correct plural form of life.
- ❌ Lifes is not considered correct in standard English.
- Use life when talking about one person, animal, or thing’s existence.
- Use lives when talking about more than one life.
Examples:
- She lived a happy life.
- Many lives were changed by the event.
- Cats are said to have nine lives.
Simple Origin or Background Explanation
English does not always form plurals by simply adding -s.
Some words ending in -f or -fe change to -ves when they become plural.
Examples:
| Singular | Plural |
| Life | Lives |
| Wife | Wives |
| Knife | Knives |
| Leaf | Leaves |
| Wolf | Wolves |
This pattern comes from older forms of English that changed certain sounds when words became plural.
Today, we simply learn these forms as spelling rules.
Because life ends with -fe, the f changes to v and es is added:
Life → Lives
That is why lifes is incorrect.
Clear Explanation of the Difference
The difference is actually very simple.
What Is “Life”?
