Dear Scholars,
There is a CBSE document (http://heritage.cbseacademic.in/blog/index.php/performing-arts/ ) on the Web dated September 2, 2012 which says the following:
"The word Kutiyattam is derived from the word ‘Kuti’ which in Malayalam language primarily means ‘combined’ or ‘together’ while ‘attam’ means acting. Therefore, the word ‘Kuttiyatam‘ means combined acting."
The above document was a product of the CBSE Research & Development Unit.
But 'Module 10 - Theatre and Drama in India' of the 'Knowledge Traditions & Practices of India' textbook edited by Kapil Kapoor and Michel Danino and probably uploaded on or after September 14, 2012 says the following on page 7.
