Aging and ageing are the same word spelled two different ways.
Aging drops the “e” before adding “-ing,” while ageing keeps it. Both describe the process of growing older, and both are grammatically correct.
Aging is the standard spelling used across most of the US. Ageing shows up more in international or British-style writing.
What Does “Aging” Mean?

Aging describes the natural process of growing older. It can function as an adjective, a verb, or even a noun, depending on how it’s used in a sentence.
Aging as an Adjective
When aging describes a noun, it acts as an adjective. Think of phrases like “an aging bridge” or “an aging population.” Here, aging simply means something that’s showing signs of getting older.
Aging as a Verb (Present Participle)
Aging is also the present participle of the verb “to age.” So “the wine is aging in the cellar” means the wine is currently going through the aging process.

Aging vs Ageing — Key Differences Explained
The difference boils down to one spelling rule: dropping or keeping the silent “e” before adding a suffix. It’s a small change, but it carries a big regional signal.
The Spelling Rule Behind the Words
Normally, words ending in a silent “e” drop that “e” before adding “-ing.” That’s why “age” becomes “aging.” The British spelling breaks this rule slightly by keeping the “e,” giving us “ageing.”
