Again, let us try the word in Malayalam for "chain". It is "changala" and pronounced with a hard "cha" sound.mahakavi wrote:
Consider the following words:
சஙà¯à®•à®¿à®²à®¿ The sa here is a soft sound (mellOsai)---sangili. When the letter "sa" occurs at the beginning of a word it gets the soft sound. But if the previous word imposes another rule as in "sinnanj ciRu", then the beginning letter of the second word gets the hard sound.
Kannadigas use the prefix "Cheluva" as in the name "Cheluvanarayana". Ask them how they pronounce it.
Among the Telugus, we have "Chinnasathyam" as in the dance guru Vempati Chinnasathyam. Do they pronounce it "Sinnasathyam"?
Derivative languages such as Malayalam, Kannada and Telugu have kept close to the original pronunciation of the Tamil words they use. It is the Tamil people who are too lazy to pronounce their language correctly.
PS. If we accept your "rules", I suppose we are living in Sennai!
