"For administrative purposes the country was divided into districts called madulu.

The word is derived from Pali mandala, an administrative district in ancient Sri Lanka, the chief of which was called a mandalika.

The names of three geographical atolls currently in use end in -madulu. In time, the meaning of madulu came to be forgotten and each administrative district was just called atolu, and its chief atolu veriya.

Some islands named Ras are small ones, and Rujjehera in Seenu is only a small islet with a handful of coconut trees. These were probably islands owned and managed by kings."
