Simple Background
The word comes from older forms of French and Latin and has been part of English for many centuries. It originally referred to the protective clothing worn by soldiers and knights during battle.
As English developed in different parts of the world, some spellings changed. British English kept armour, while American English simplified it to armor. This pattern also appears in other words, such as colour/color, favour/favor, and honour/honor.
Today, both spellings are accepted, but each belongs to a different variety of English.
Understanding the Difference
The meaning does not change.
Both armour and armor refer to:
- Protective clothing worn in battle.
- Protective covering on military vehicles.
- Any material used to protect people or objects.
The only real difference is the spelling.
