Ageing and aging are both correct spellings of the same word — the only difference is regional convention.
Aging (without the e) is standard in American and Canadian English, while ageing (with the e) is preferred in British, Australian, and Commonwealth English.
This guide breaks down the difference between ageing and aging, which spelling to use for your audience, and one important exception that applies everywhere.
What Does Aging / Ageing Mean?
Both spellings describe the same thing — the process of growing older or deteriorating over time. The word functions as both a verb (the ongoing act of getting older) and an adjective (describing something related to the aging process).
As a verb: “The cheese is aging in the cellar.” “The population is ageing rapidly in many developed countries.”
As an adjective: “Aging infrastructure is a serious concern for many cities.” “An ageing workforce presents unique challenges for employers.”

Aging vs Ageing — The Regional Difference
The difference between these two spellings is entirely about geography and audience — not grammar or correctness.
Aging — American and Canadian English
Aging (no e) is the standard spelling in American and Canadian English. It follows the general American English pattern of dropping the silent e from a verb before adding -ing:
- age → aging (American)
- dance → dancing
- make → making
This pattern prioritizes brevity and phonetic simplicity — removing letters that do not affect pronunciation.
Example: “The National Institute on Aging funds research into age-related diseases.”
Ageing — British, Australian, and Commonwealth English
Ageing (with e) is preferred in British, Australian, and most Commonwealth varieties of English. These varieties tend to retain the silent e in certain words — particularly where dropping it might affect readability or follow a less consistent pattern.
Example: “The ageing population in the United Kingdom is placing greater demands on the National Health Service.”

The Important Exception — Ageism
Regardless of which regional spelling you use for aging or ageing — the noun ageism is always spelled without the e. There is no ageing equivalent here — only ageism is accepted in all standard dictionaries across all English varieties.
Example: “Ageism in the workplace remains a significant barrier for older employees seeking new positions.”
This applies whether you write aging or ageing everywhere else in your document — ageism stays the same.
Why the Spelling Difference Exists
The aging / ageing split reflects a broader pattern in how American English and British English handle words that end in a silent e before adding a suffix.
American English — influenced by spelling reformers like Noah Webster in the 18th and 19th centuries — moved toward dropping unnecessary letters for simplicity and efficiency.
British English retained more traditional spellings, preserving the e in certain words either for historical consistency or to signal pronunciation and word relationships more clearly.
This same pattern creates other familiar spelling differences:
None of these pairs is correct or incorrect in an absolute sense — they simply reflect different regional conventions that have developed over centuries.
Which Spelling Should You Use?
The golden rule: Choose the spelling that matches your audience — and stay consistent throughout your document. Switching between aging and ageing in the same piece of writing looks inconsistent, even though both are technically correct.
Common Mistakes to Avoid
Memory trick:
- Aging → American → short and streamlined, like American English preferences
- Ageing → British → retains the e, like British English spelling traditions
- Ageism → always the same everywhere — no e in the middle, no exceptions
FAQs — Ageing vs Aging
Which is correct — aging or ageing?
Both are correct — they are regional variants of the same word. Aging is standard in American and Canadian English. Ageing is preferred in British, Australian, and Commonwealth English. Neither is wrong — your audience determines which to use.
Is it aging or ageing in the US?
In the United States, aging (without the e) is the standard and preferred spelling. You will see it consistently in American publications, government documents, and academic writing. The National Institute on Aging, for example, uses the American spelling.
What happens to your body after 80?
After 80, the aging process typically accelerates across multiple body systems — bone density decreases further, muscle mass continues to decline, cardiovascular efficiency reduces, and cognitive processing may slow. Immune function weakens, making recovery from illness longer. Regular movement, nutrition, social connection, and medical care all play significant roles in healthy aging beyond 80.
What vitamins help with aging?
Several vitamins and nutrients are associated with supporting healthy aging — including Vitamin D (bone and immune health), Vitamin B12 (nerve and cognitive function), Vitamin C (skin and immune support), Vitamin E (antioxidant protection), and Omega-3 fatty acids (heart and brain health). Consulting a healthcare provider is always the best step before beginning any supplement regimen.
Conclusion
Aging and ageing are two spellings of the same word — correct in different parts of the world. Aging is the American and Canadian standard. Ageing is the British and Commonwealth preference. Both describe the same process of growing older or deteriorating over time.
Choose the spelling that matches your audience and stay consistent throughout your writing. The one universal rule — regardless of which form you use — is that ageism is always spelled without the e in the middle. Get that right and your writing will always be accurate, regionally appropriate, and professionally consistent.
