Mal: കടുത്തുരുത്തി kaṭutturutti

‘Sea Island’    Town, Kerala

From Mal:  kaṭal‍/kaḍal, ‘sea’; and turutti, island

Kaduthuruthy used to be on the coast (i.e. the complex pattern of seawater lagoons and backwaters that make up the coastline here): a 14thC text describes its ‘grand harbour’. It is likely like an earthquake and/or tsunami shifted the coastine westwards.

It is still very much a river front resort surrounded by water.
