The Origin of Ageing or Aging
The word age comes from Old French aage and Latin roots related to time and lifespan.
When English speakers created the present participle form, they added -ing to age. Over time, different spelling traditions developed.
British English generally keeps the extra e before adding -ing, creating ageing. American English simplified the spelling and adopted aging as the standard form.
Although both forms have existed for centuries, regional writing standards eventually made one spelling more common in the UK and the other more common in the United States.
