Have you ever wondered whether Lily or Lilly is the correct spelling? The confusion is understandable because both forms are widely seen, especially when talking about a person’s name. However, the answer depends on context.
If you mean the flower, lily is the standard English spelling. If you mean a person’s name, Lily and Lilly can both be correct because people may have different official or preferred spellings.
In this guide, you’ll learn the difference between Lily and Lilly, how each spelling is used, the correct plural form, British and American usage, common mistakes, and when you should choose each version.
Lily or Lilly: Quick Answer
Is Lily or Lilly Correct?
Lily is the standard spelling for the flower.
Lilly can be correct when it is a person’s name, surname, company name, or another proper name that officially uses the double l.
The easiest rule is:
| Word | Common Use | Correct? |
|---|---|---|
| lily | Flower | Yes |
| Lily | Personal name | Yes |
| Lilly | Personal name | Yes |
| Lilly | Standard spelling of the flower | No |
| lilies | Plural of lily | Yes |
| lillies | Plural of lily | No |
For example:
- The lily is blooming in the garden. ✅
- Lily is coming to dinner. ✅
- Lilly is coming to dinner. ✅
- The lilly is blooming in the garden. ❌
- The garden has several lilies. ✅
So, if you are writing about the flower, use lily. If you are writing someone’s name, use the spelling that person actually uses.
Lily or Lilly: The Simple Rule
Think of it this way:
Flower = lily
Person = Lily or Lilly, depending on the person’s name
This distinction solves most Lily vs. Lilly spelling questions.
What Does Lily Mean?
Lily as a Flower
Lily is a noun referring to various flowering plants. Cambridge Dictionary defines a lily as a plant with large, bell-shaped flowers on a long stem, while Oxford lists lilies as its plural form.
Examples include:
- The white lily looked beautiful in the garden.
- She placed a lily in the vase.
- The lily needs enough sunlight to grow.
- Several lilies were blooming beside the walkway.
The word is normally written with one l after the initial capital or lowercase letter:
Lily
not:
Lilly
Lily as a Personal Name
Lily is also a common given name. Oxford Learner’s Dictionaries lists Lily as a girl’s first name.
For example:
- Lily joined our class today.
- I sent Lily an invitation.
- Lily loves gardening.
- Have you spoken to Lily?
Here, the word is capitalized because it is a proper name.
The important point is that the same spelling can refer to either a flower or a person. Context tells you which meaning is intended.
Lily: Meaning and Origin
The word lily has a long linguistic history. Oxford traces it through Old English lilie to Latin lilium and Greek leirion.
That history helps explain why the modern English spelling is lily, rather than lilly.
The flower name has also become a popular personal name because flower names are commonly used as given names.
What Does Lilly Mean?
Lilly as a Personal Name
Lilly is an established spelling used for personal names. The extra l makes it visually different from Lily, even though the two names are generally pronounced the same.
For example:
- Lilly sent me a message.
- I met Lilly at school.
- Lilly is studying English.
- Please give the letter to Lilly.
If someone’s official name is Lilly, you should not change it to Lily simply because Lily is the standard spelling of the flower.
Names can have individual spellings, family traditions, and established variants.
Is Lilly a Misspelling of Lily?
Not necessarily.
When Lilly refers to a flower, it is not the standard spelling. But when Lilly is someone’s name, it can be completely correct.
Compare these sentences:
The lily smells wonderful.
Lilly smells the flowers.
The first sentence uses lily as a common noun. The second uses Lilly as a person’s name.
Therefore, calling every use of Lilly a spelling mistake would be incorrect.
Lily vs. Lilly Pronunciation
In ordinary English pronunciation, Lily and Lilly are generally pronounced the same way: approximately LIL-ee. Cambridge gives the pronunciation of lily as /ˈlɪl.i/.
This identical pronunciation is one reason the spelling can be confusing.
If someone says:
“My name is Lily.”
you cannot always know from pronunciation whether the person spells it Lily or Lilly.
The safest approach is to check the person’s preferred spelling.
Lily or Lilly in British and American English
Is Lilly the British Spelling?
No.
The difference between lily and lilly is not a British-versus-American spelling difference.
Both British and American English use lily as the standard spelling of the flower. Cambridge provides the same basic word and pronunciation for UK and US English.
For example:
British English:
The lily is growing in the garden.
American English:
The lily is growing in the garden.
There is no need to change lily to lilly when switching between these varieties of English.
Lily vs. Lilly for Names
Personal names work differently.
A person in the United Kingdom may be named Lilly, while another person in the United States may be named Lily.
Both names can be correct because proper names are not required to follow the spelling of related common nouns.
For example:
- Lily Brown may be the correct name of one person.
- Lilly Brown may be the correct name of another person.
Always use the spelling associated with the individual.
Comparison Table
| Situation | Correct Form | Example |
|---|---|---|
| Flower | lily | The lily is blooming. |
| More than one flower | lilies | The lilies are beautiful. |
| Common female name | Lily | Lily called me. |
| Variant personal name | Lilly | Lilly called me. |
| British flower spelling | lily | The lily is white. |
| American flower spelling | lily | The lily is white. |
| Company/proper name | Follow official spelling | Use the registered name. |
Lily or Lilly: Real-Life Example and 2025–2026 Name Data
A Real-Life Context Example
Imagine that an editor is proofreading a gardening article. The article contains the sentence, “The lilly produces beautiful flowers.” At first glance, the spelling may look reasonable because the editor has seen Lilly many times online. However, the sentence is talking about the plant, not a person. The correct sentence is therefore, “The lily produces beautiful flowers.”
Now imagine that the same article includes this sentence: “Lilly Johnson grows flowers in her backyard.” In this case, Lilly should not be changed to Lily unless there is evidence that the name was typed incorrectly. The writer is referring to a specific person whose name may officially be spelled Lilly.
This example shows why spelling cannot always be judged by appearance alone. Lily is the standard common noun for the flower, while Lilly can be a legitimate proper name. The surrounding sentence provides the context needed to choose the correct form.
The distinction becomes especially important in professional writing. Changing a person’s name because it resembles a common dictionary word can introduce an actual error. At the same time, allowing a spelling such as “lilly” to remain in a botanical sentence creates a standard spelling mistake. The correct choice depends on what the word represents.
2025–2026 Name Popularity Data
Recent U.S. Social Security Administration data also shows that both spellings are used as given names.
For births in 2025, Lily ranked #18 among U.S. girl names, up from #24 in 2024. Lilly ranked #252 in 2025, up from #261 in 2024.
The SSA’s data is based on Social Security card application records and represents a 100% sample of its records as of March 2026, subject to the agency’s stated data limitations.
The data provides useful context: Lily and Lilly are both established personal-name spellings, but they are not interchangeable when referring to an individual.
The SSA also reports that Lily ranked 29th among girls’ names for the 2020–2025 period, with 35,872 occurrences in its data for those six years.
These figures concern names, not the spelling of the flower. Therefore, they should not be interpreted as evidence that lilly is an alternative dictionary spelling of the plant.
What the Data Tells Us
The recent naming data supports three practical observations:
- Lily is an established personal name.
- Lilly is also an established personal name.
- Name popularity does not change the standard spelling of the flower.
So, whether you’re writing a baby-name article, editing a personal profile, or describing flowers, always identify the context first.
Common Mistakes With Lily and Lilly
Mistake 1: Writing Lilly for the Flower
Incorrect:
The lilly is my favorite flower.
Correct:
The lily is my favorite flower.
The standard dictionary form is lily. Both Cambridge and Oxford use this spelling for the flower.
Mistake 2: Using the Wrong Plural
Incorrect:
The garden has five lilys.
Correct:
The garden has five lilies.
The plural changes from y to ies:
lily → lilies
Oxford and Cambridge both identify lilies as the plural form.
Mistake 3: Writing “Lillies”
Incorrect:
The vase contains beautiful lillies.
Correct:
The vase contains beautiful lilies.
The standard plural of lily is lilies, not lillies.
The double l in a personal name such as Lilly does not change the spelling of the flower.
Mistake 4: Automatically Correcting Someone’s Name
Suppose a person writes:
My name is Lilly.
Do not automatically change it to:
My name is Lily.
If Lilly is the person’s actual name, that spelling is correct for that individual.
A person’s name should be reproduced accurately, especially in emails, certificates, records, publications, and professional documents.
Mistake 5: Assuming It Is a UK-US Difference
Incorrect assumption:
Lilly is the American spelling and lily is the British spelling.
That is not the case.
For the flower, both varieties use lily.
The difference is primarily one of context when Lilly appears as a proper name.
A Quick Editing Checklist
Before choosing Lily or Lilly, ask:
- Am I talking about the flower? → Use lily.
- Am I talking about more than one flower? → Use lilies.
- Am I writing someone’s name? → Check the person’s actual spelling.
- Is the word part of a company or brand name? → Follow the official spelling.
- Am I switching between British and American English? → Keep lily for the flower.
- Am I unsure about a person’s name? → Check their preferred or official spelling.
This simple checklist can prevent nearly all common Lily vs. Lilly errors.
