Unittiri.--Unittiri, or Unyatiri, meaning, it is said, venerable boy, has been recorded as a sub-division of Samantam. Unnittan appears, in the Travancore Census Report, 1901, as a title of Nayars, and is said to be derived from unni, small, tan, a title of dignity. Unnekankana.--A sub-division of Kurubas, who tie a woollen thread (unne kankana) round the wrist at times of marriage. Unni.--For the following note on the Unnis of Travancore, I am indebted to Mr. N. Subramani Aiyar. The word Unni, whatever its significance may have been of old, at present forms the common title of four castes of the Ambalavasi group, whose manners and custom differ considerably in their details. They are known, respectively, as Pushpakans, Brahmanis, Tiyattunnis, and Nattu Pattars, their social precedence being in this order. Pushpakan comes from pushpa, which in Sanskrit means either a flower or menses. Brahmanis, more vulgarly known as Pappinis, are so named because they perform some of the priestly functions of the Brahmans for the Sudra population of Travancore. Tiyattunnis, also known as Taiyampatis in British Malabar, are so called from the peculiar religious service they perform in some Hindu temples. Nattu Pattars are also known as Pattar Unnis and Karappuram Unnis. Unni means a child, and is used as an honorific term to denote the male children of a Nambutiri's household. The reason why these Ambalavasi castes came to be so called was that they were looked upon as more respectable than the Nayars, by whom the term must doubtless have been made use of at first. The Pushpakans are said to be divided into three classes, namely Pushpakans, Nambiassans, and Puppallis. The first section live only as far south as Evur in Central Travancore, and are called Nambiyars in the north. The Nambiyassans live in Cochin and North Travancore, while the Puppallis are found only towards the south. There are no sub-divisions among the Brahmanis and Karappuramunnis. But the Tiyattunnis are divided into two classes, namely the Tiyatinambiyans of the north, who are generally employed in the temples of Sastha, and Tiyattunnis proper, who perform a similar function in the shrines of Bhadrakali. Women are also known as Atovarammamar and Kovillammamar.
