The Origin of Ageing or Aging
Where the Word Comes From
The word age comes from Old French age, which entered English through Latin aetas, meaning “period of life” or “lifetime.” The verb to age developed naturally to describe the process of becoming older over time.
Why Two Spellings Exist
Originally, English spelling followed a more phonetic pattern. When adding -ing to age, British English kept the e, forming ageing, to preserve pronunciation clarity. American English later simplified many spellings by dropping silent letters, resulting in aging.
Influence of American Spelling Reform
In the 18th and 19th centuries, American English moved toward simplified spelling. Just as ageing became aging, other words changed as well:
- colour → color
- centre → center
- travelling → traveling
This is why both spellings exist today and are considered correct.
