Definition of spare

The word "spare" has its roots in Old English and Old Norse. In Old English, the word "spēr" meant "left over" or "remaining", and it was often used to describe a part or element that was left over after a process or transaction. For example, a spēr of food might refer to a leftover portion. In Old Norse, the word "spyrja" meant "to spare" or "to leave over", and it was often used in the context of warfare or battle. For example, a spyrja of troops might refer to a reserve force that was left untouched during a battle. Over time, the spelling and meaning of the word "spare" evolved, and it came to be used in a variety of contexts, including sports (e.g. a spare tire on a car), business (e.g. a spare employee), and everyday life (e.g. spare time). Today, the word "spare" is used to describe anything that is left over or in reserve, whether it's a physical object, a person, or a concept.
