The thamil grammerians have divided the 18 consonants into six hard.six soft and six midle letters.

The six hard sounding letters are called vallina erluttu ( வல்லின ஏழுத்து ) ;
 they are : க ,ச,ட,த,ப,ற . ( Ka,Sa,Ta,Tha,Pa,Ra )

The six soft sounding letters are called mellina erluttu ( மெல்லின ஏழுத்து ) ;
 they are :  ங,ஞ,ண,ந,ம,ன

The middle  letters are called ideyina erluttu ( இடையின  ஏழுத்து ) ;
 they are : ய,ர,ல,வ,ழ,ள
