“Aging” and “ageing” are two accepted spellings of the same word that describe the process of growing older or becoming older over time. The meaning is identical, but spelling differs based on regional English conventions. American English prefers “aging,” while British English and many Commonwealth regions prefer “ageing.”
Which Spelling Is Correct?
Both spellings are correct:
- Aging → American English standard and dominant in scientific writing
- Ageing → British English and Commonwealth standard
The difference is stylistic, not grammatical or semantic.
Why Are There Two Spellings?
The word developed from Old French aage, which influenced Middle English forms related to “age.” Over time:
- American English simplified spelling conventions and dropped the “e,” forming aging
- British English retained the traditional spelling ageing
Both forms remain correct due to independent regional standardization.
