Karaikal North and Karaikal South
Karaikal is a city and a municipality in Karaikal district of Puducherry. The name Karaikal is a combination of two words `Karai` and `Kal`. Both the words ‘Karai and `Kal` have several meanings, of which the more acceptable ones are `lime mix` and `canal` respectively. Hence it has been suggested that the name may mean a canal built of lime mix. However, no trace of such a canal is evident now. Karaikal town about 16 km north of Nagappattinam and 9 km south of Tarangambadi is the regional headquarters. Karaikal port is a new deep sea water port being constructed in Vanjore, Karaikal.
