The name implies that the village has many plantations and harbors. From this village a salt lake mixes with others after running a distance of 4 km. In the early days of the village people used to trade using catamarans to board their goods in to steamers which trade with Malaysia, Singapore, Sri Lanka and other South East Asian countries. The people started calling them 'Marakalayar' and now they are called as 'Maraikayar'. They started trading by way of a barter system. The people take the goods in night by horseback and traded them in the markets in the daytime. These people are called 'Tatharkal', as the days passed they are now called as 'Iravuthur'. This name doesn't relate to a religion they are called so because of their trade. They are no longer called by that name now. Only few are now doing business, some have become agriculturists and the majority of the people are working in foreign countries.
