Karaikal district
Karaikal district (French: District de Karikal) is one of the four districts of the Union Territory of Puducherry in India. Etymology

The origin of the word Karaikal is uncertain. The Imperial Gazetteer of British  India gives its meaning as 'fish pass'. 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. Geography
