Tharavadu

പലേരി തറവാട് 

Tharavadu(XdhmSv) is a system of joint family practiced by Malayalis, Each Tharavadu has a unique name. As joint families grew and established independent settlements, the Sakhas (branches) modified the names in a such way that the main Tharavadu names are identifiable, yet Sakha (or "Thavazhi", i.e. Thay Vazhi which means "Through Mother") had a distinct name. 

For communities like Nairs, the "Tharavad name" is identified through their mother's house.

Karanavar

The Tharavadu was administered by the Karnavar, (കാരണവര്‍)  the senior most male member of the family. He will be the eldest maternal uncle of the family as well. The members of the Tharavadu consisted of mother, daughters, sons, sisters and brothers. The fathers and husbands had only very minimal role to play in the affairs of the Tharavadu. 

The Karanavar took all major decisions. He was usually autocratic. However, the consent of the eldest female member of the family was taken before implementing the decisions. This eldest female member would be his maternal grandmother, own mother, mother's sister, his own sister or a sister through his maternal lineage. 

Since the lineage was through the female members, the birth of a daughter was always welcomed. Each Tharavadu also has a Bhara Devatha (clan deity) revered by those in the particular Tharavadu. Temples were built to honour these deities.
