The word "kiri" means "to cut off". The word "tory" has several possible origins, including:
- From the Irish name "Dara", which means "oak tree". This is possible because oak trees have long been associated with strength and endurance.
- From an Old English word meaning "a lookout or watchman". This is also possible because watchmen were often stationed at the entrance to a city or fortress, and might be said to "guard" it.
- From an Old English word meaning "a warden or keeper of an estate". This is possible because wardens were responsible for protecting and maintaining property, and might be said to "guard" it.
