Sunni
From dKosopedia
Sunni Islam (سنّة) is the largest denomination of Islam. Followers of the Sunni tradition are known as Sunnis or Sunnites.
It is widely believed among Sunnis that the name Sunni derives from the word Sunnah which represents the prophet Muhammad's manner of conduct. Some have argued that "Sunni" actually means or is derived from a word that means "a middle path" referring to the idea that Sunnism is a more neutral position than the perceivedly more extreme viewpoints of the Shias and the Kharijites.
