The Jewish Aryans that landed in the Kerala coast subdued the locals and became the 'Highers' of the land. These are the Namboodhirees. The language that developed as an intermediary between the Thamizh speaking locals and the foreign invaders came to be known as Sanskrit. Sanskrit means well made up, cooked up or well put together. However, the locals were so much influenced by the Brahmins that Sanskrit dominated their spoken language rather than Thamizh. Thus came into being a language with a Thamizh-like dialect and Sanskrit words. This is Malayalam.

Namboodhirees were the highest ranked class in the caste system. The original people were Naagars - the Thamizhar. They refused to be called a lower class. So, they started imitating the manners and language of the Namboodhirees. These are the Nairs of Kerala (and nayakars of Karnataka and Thamizhagam, the Naidus of Andhra and the Naiks of Odissa and elsewhere). Eg. Nair wives still call their husbands 'Yettan' as do the Brahmins 'Anna'. (Jews 'brothers' married their sisters, though not the siblings).

Nairs were a bold and courageous people and became the bodyguards and soldiers for the Namboodhirees. The Brahmins exploited the Nairs and the Nair women had multiple male partners giving rise to a Polyandric society. However much they have tried, Nairs still have not been able to attain to their ambitions and are still classified as a lower caste alongside the Daliths. (Interestingly, the modern-day Jews also trace their Jewish roots through their mothers, not fathers).
