The Origin of Aging or Ageing
The word age comes from the Latin word aetas, meaning “lifetime” or “period of life.” It entered English through Old French many centuries ago.
To create the present participle or verbal noun, English usually adds -ing to verbs.
For many verbs ending in -e, the final e is dropped before adding -ing.
Examples:
- make → making
- drive → driving
- write → writing
Following this rule, age naturally becomes aging.
However, in British English, the spelling ageing became common because many writers preferred keeping the e for easier reading and pronunciation. Over time, both spellings became accepted in different parts of the English-speaking world.
Today:
- Aging dominates American English.
- Ageing dominates British English.
Neither spelling changes the meaning.
