Madras Bashai மெட்ராஸ் பாஷ (Madras Slang) is a cockney of Tamil language and English language spoken in the city of Chennai (previously known as Madras) in Tamil Nadu, India. The word bashai derives from the Sanskrit word bhasha, meaning "language", which means Mozhi in Tamil. Madras Bashai is a loose polyglot blend of Tamil with Indian English, Telugu, Kannada and Hindustani language. Madras bashai has been largely popularized by autorickshaw drivers and fishermen from the northern parts of the city.this slag is spoken in Chennai Tiruvallur kanchipuram vellore districts of north tamilnadu.
Madras Bashai evolved largely during the past three centuries. It grew in parallel with the growth of cosmpolitan Madras. After Madras Bashai became somewhat common in Madras, it became a source of satire for early Tamil films from the 1950s, in the form of puns and double entendres. Subsequent generations in Chennai identified with it and absorbed English constructs into the dialect, making it what it is today.
Due to immigration and cultural exchange, terms from Madras Bashai are widely spread and are also used sometimes in other cities and towns of South India.
Madras Bashai evolved largely during the past three centuries. Madras was founded in 1640 by the British East India Company, and with its emergence as an important city in the British Empire and as the capital of Madras Presidency, the contact with western world increased and a number of English words crept into the vocabulary. Many of these words were introduced by educated, middle class Tamil migrants to the city who borrowed freely from English for their daily usage. Due to the presence of a considerable population of Hindustani-speakers, especially, the Gujaratis, Marwaris and some Muslim communities, some Hindi words, too, became a part of Madras Bashai. At the turn of the 20th century, the Tamil spoken by the Brahmins of Madras city was considered to be standard spoken Tamil. Though preferences have since shifted in favor of the Central and Madurai Tamil dialects, the English words introduced during the early 20th century have been retained.
