US vs. UK English: Spelling Differences Explained
The spelling of “ageing” vs “aging” fits into a broader trend of divergence between American English and British English.
Why These Differences Exist
In the early 1800s, Noah Webster, an American lexicographer, advocated for spelling reform to simplify English. His influence led to American spellings such as:
- Color instead of Colour
- Center instead of Centre
- Honor instead of Honour
- Aging instead of Ageing
This move toward simplification and phonetic consistency is why “aging” dropped the silent “e.”
Key Takeaway
If you’re writing for an American audience, use “aging.” For UK or Commonwealth readers, stick with “ageing.”

Linguistic Origins and Etymology of ‘Ageing’ and ‘Aging’
The root word “age” traces back to Old French “aage” and Latin “aetas,” meaning time or age.

Why the “E” Was Dropped in American English
- American spelling tends to simplify.
- Silent letters (like the “e” in “ageing”) were dropped to make spelling more logical and phonetic.
British English retained the “e” for stylistic and historical reasons.
