The word Nair is said to be originated from Naya(Dog),implying that they were loyal to their Brahmin and kshtryia masters.Even today they give undue respect to those community members unlike the rest of malayalees.Though there are a few cases of Nairs becoming Naduvzhi's can be compared to a watcher or a peon becoming a manager of a company.Kerala's kshtriya and Brahmin community were so small that they needed help to look after their land and other assets.So some of the watchers became small time rulers.Therefore this cannot be applied to a whole society.Earlier dutch visitors to kerala has protrayed Nairs a group of mercineries doing anything for money while they were proud to have their females sleeping with the upper caste men!
