Key Differences

Demeanour, as used in British English, signifies the outward physical manifestation of a person's character or mood, particularly as it affects others. On the other hand, Demeanor is the American English spelling of the same term, reflecting identical meanings and usage in contexts involving someone's conduct or appearance.
While demeanour is commonly found in British English texts, encompassing literature, official documents, and day-to-day communication, Demeanor is prevalent in American English, adhering to the linguistic norms of the United States in books, media, and conversations.
Demeanour is often associated with the traditional British English spelling conventions that include extra vowels in certain words (e.g., colour, honour), whereas Demeanor follows the American English convention of simplifying spelling by omitting unnecessary letters.
The pronunciation of demeanour and demeanor may slightly vary between British and American English speakers due to accent differences, but the distinction is minimal, and both terms are easily understood across English-speaking regions.
In educational settings, British schools and universities teach the spelling and usage of demeanour in accordance with UK English standards, while American educational institutions teach demeanor, reinforcing the spelling and usage norms of American English.
