If you have ever written about getting older, growing older, or the natural process of becoming older, you may have wondered whether the correct spelling is ageing or aging.
Both forms are correct, but the one you should use depends largely on the variety of English you are writing in.Ageing is the traditional spelling used in British English and many other varieties of English.
Aging is the standard spelling in American English and is also widely used internationally, particularly in American-influenced writing.
The difference can be confusing because most English words ending in -ing do not require you to remove a letter from the base word.In this case, however, the spelling follows different conventions on each side of the Atlantic.
The good news is that there is no need to memorize two completely different meanings. Ageing and aging have the same meaning, pronunciation, and grammatical function. The main difference is regional spelling.
Quick Answer: Ageing or Aging?
Both “ageing” and “aging” are correct spellings.
- Ageing = preferred in British English
- Aging = preferred in American English
- Both mean the process of becoming older or showing the effects of growing older
- Both can function as a verb form, adjective, or noun-related form depending on context
- The pronunciation is essentially the same
Examples
British English:
The population is ageing rapidly.
American English:

Neither sentence is grammatically wrong. The choice depends on the English variety being used.
What Does “Ageing” or “Aging” Mean?
Ageing and aging refer to the process of becoming older over time. The words can describe people, animals, objects, materials, systems, or populations.
For example:
The ageing population is creating new challenges for healthcare systems.
Here, ageing describes a population that has an increasing proportion of older people.
The words can also describe something that has existed or been used for a long time:
The aging building needs extensive repairs.
In this sentence, aging means that the building is becoming older and may be showing the effects of time.
The two spellings do not have different meanings. The difference is primarily one of regional spelling convention.
Simple Definition
Ageing/Aging: the process of becoming older or developing characteristics associated with age.
Depending on context, it can describe:
- people growing older
- an aging population
- aging skin
- aging technology
- aging buildings
- aging materials
- the aging process
Ageing vs. Aging: What Is the Difference?
The key difference is where the spelling is used.
| Spelling | Main Usage | Example |
|---|---|---|
| Ageing | British English | The population is ageing. |
| Aging | American English | The population is aging. |
Both spellings come from the verb age.
The difference becomes especially noticeable when writing for a specific audience. If your article is aimed primarily at readers in the United States, aging will usually look more natural. If you are following British English conventions, use ageing.
Ageing in British English
British English normally keeps the e before -ing:
She is ageing gracefully.
The ageing population needs more support.
Scientists are studying the effects of ageing.
This spelling is also common in other varieties influenced by British English.
Aging in American English
American English generally drops the e:
She is aging gracefully.
The aging population needs more support.
Scientists are studying the effects of aging.
This is the standard spelling for American audiences.
Why Is It “Ageing” in British English but “Aging” in American English?
The difference comes from different spelling conventions rather than a difference in pronunciation or meaning.
English has several words in which British and American spelling conventions differ. Some differences are widely recognized, such as:
- colour / color
- favour / favor
- travelling / traveling
- cancelled / canceled
The ageing/aging distinction follows a similar regional pattern.
British English commonly retains the e in ageing, while American English commonly uses aging.
It is therefore better to think of the two spellings as regional variants, rather than calling one correct and the other incorrect.
Is “Ageing” or “Aging” More Common?
Usage depends heavily on the region.
For American English, aging is the normal choice.
For British English, ageing is the traditional standard spelling.
You may still encounter aging in British publications, especially in scientific, medical, business, or international contexts influenced by American usage. Likewise, American readers will generally understand ageing without difficulty.
For consistent writing, however, it is best to choose the spelling that matches the variety of English you are using throughout the article.
How Do You Pronounce “Ageing” and “Aging”?
Both spellings are pronounced essentially the same way.
Ageing / Aging → approximately AY-jing
The spelling changes, but the pronunciation does not normally change.
The word comes from age, so the first syllable has the same sound as the beginning of agent or the word age itself.
This is one reason the spelling difference can be confusing: readers hear the same word but may see either ageing or aging depending on the writer’s preferred variety of English.
Is “Ageing” or “Aging” a Verb?
Yes. Ageing and aging can be the present participle and gerund forms of the verb age.
The verb age means to become older or to cause something to become older.
As a Verb
The population is ageing rapidly.
(British English)
The population is aging rapidly.
(American English)
In both sentences, the meaning is exactly the same.
As a Gerund
The word can also function as a noun when it refers to the process of becoming older.
Ageing is a natural part of life.
Aging is a natural part of life.
Again, the spelling depends on the variety of English.
Ageing vs. Aging in British and American English

Common Mistakes With “Ageing” and “Aging”
Thinking One Spelling Is Wrong
A common mistake is assuming that ageing is a misspelling of aging, or that aging is incorrect because British English uses ageing.
Both are standard spellings.
The correct choice depends on the variety of English.
Mixing British and American Spelling
Using aging in one paragraph and ageing in another can make an article look inconsistent.
For example:
The aging population is growing, and the ageing workforce needs additional support.
There is nothing inherently ungrammatical about this sentence, but if the article is written in one consistent variety of English, switching between the two forms is unnecessary.
Assuming the Pronunciation Is Different
The two spellings are normally pronounced the same way.
The extra e in ageing does not create a different pronunciation.
Confusing “Aging” With a Different Word
Some learners think aging has a completely different meaning from ageing.
It does not.
Aging skin
and
Ageing skin
mean the same thing.
The difference is spelling convention, not vocabulary.
Using “Aging” in a British-English Article Without a Reason
While British readers will understand aging, writers following British English style will generally prefer ageing.
Likewise, American writers normally choose aging rather than ageing.

Ageing vs. Aging in Formal and Informal Writing

The study examines the effects of aging on memory.
In British English, ageing can be used in the same contexts:
The study examines the effects of ageing on memory.
The important point is to follow the style of the publication, institution, or audience you are writing for.

If your website primarily targets U.S. readers, aging will generally be the more natural primary spelling.
If your audience is primarily in the UK, ageing is the better choice.
You can still mention the alternative spelling naturally when it helps readers:
Aging, also spelled ageing in British English, refers to the natural process of becoming older.
