The Origin of Ageing or Aging
The word age comes from the Old French word aage, which came from the Latin word aetas, meaning “lifetime” or “period of life.”
The verb age later developed into ageing/aging, meaning “to grow older.”
The spelling difference appeared because British and American English evolved differently.
- British English usually keeps the extra e before adding -ing, creating ageing.
- American English often drops the silent e before adding -ing, resulting in aging.
Over time, dictionaries accepted both spellings because each follows its regional standard.
