Karaikal is a place in India state of Puducherry located at the longitude of 79.8506606 and the latitude of 10.9124963.
Karaikal also Karikal or Karaikkal also called as (thalai gnayiru), is a city and a municipality in Karaikal district in the Union Territory of Puducherry, India. Several explanations are offered for the word 'Karaikal'. The imperial Gazetteer gives it the meaning 'fish pass'. According to Julien vinson the town is said to have known as Karaigiri in Sanskrit. However, the name Karaikal is no doubt 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.
