The term Chettiar or Chetty or "Shetty" is a title used by various mercantile castes in South India, especially in the states of Tamil Nadu and Kerala. In Tamil Nadu, 14% of the population is Chettiar. "Chetty" derives from the Sanskrit word "Shreshti" meaning "wealth", and is related to other castes in India like, "Setji" of the Marwaris of Rajastan, Sethi or Seth of Punjab, and Shetty or Setty of Karnataka all of which are mercantile castes with variations of the same root word.
Chettiar communities claim the Vaishya (merchant) varna within Hindu society. The Nattukottai Chettiar are elite bankers. The Vaniya Chettiars are known for running oil mills and selling groceries (food grains).[better source needed] The Chettiars are considered to be among the pioneers of organised banking in the country. They are also credited with introducing the concept of double entry bookkeeping, 'Pattru Varavu' in Tamil, commonly known as debit and credit. This community from the south of Tamil Nadu has left a silent signature on everything from manufacturing to banking, fertiliser and films.
