[|Human|] What were all the earlier names for the city presently known as Chennai?
[|AI|] Chennai traces its roots back to a fishing village called Madrasapattinam. The British officially named it Madras when they purchased the land in the 17th century. The name of the city was changed to Chennai in 1996.
