ஃ

ḥ   . The guttural letter called ஆய்தம் and inserted by Tamil grammarians be tween the vowels and consonants as not properly belonging to either; it occurs only after a short initial and before a hard letter--as அஃகம், எஃகுதல், அஃது. This letter is found only in poetic language and is often inserted merely to fill up the verse. Children in learning the alphabet write it கூ and call அக்கேன or அக்கேனம்.
