Late in the afternoon, a blogger paused while editing an article and noticed something odd. One source used ageing, another preferred aging—both in serious publications like news sites and medical journals.
Curious, she searched ageing or aging, just like thousands of students, writers, and professionals do every day. How could two spellings both be right?
The answer lies in geography, not meaning. Ageing or aging describe the same process of growing older, but British English favors ageing while American English prefers aging.
For anyone writing internationally or working in SEO, that choice suddenly matters.
This guide clears things up with a quick answer, background on spelling rules, real-world usage, common mistakes, and how search trends differ by country, so you’ll know exactly when to use ageing or aging with confidence.
Quick Answer
Both ageing and aging are correct spellings.
- Aging → American English
Example: The US population is aging rapidly. - Ageing → British English
Example: The UK is facing challenges related to an ageing society.
They mean the same thing. The only difference is regional spelling preference.
The Origin of Ageing or Aging
The word comes from the verb “age”, which entered English from Old French aage, meaning “stage of life.” Over time, English developed different spelling systems.
In British English, verbs that end in -e often keep the “e” when adding -ing:
- age → ageing
- queue → queueing
American English simplified many spellings in the 19th century, influenced by Noah Webster. The goal was to make spelling more phonetic and efficient:
- age → aging
- colour → color
That’s why both forms exist today.
British English vs American English Spelling
The difference follows a clear pattern.
Key Rule
- British English: keeps the “e” → ageing
- American English: drops the “e” → aging
