Origin and History
The word age comes from the Latin word aetas, meaning “lifetime” or “period of life.”
As English evolved, verbs ending in -e followed different spelling patterns in British and American English.
British English often keeps the extra “e” before adding -ing, producing ageing.
American English usually drops the extra “e”, creating aging.
Over time, both spellings became accepted within their own language standards.
