ABSTRACT
As has been mentioned in the chapter of kana, there are 48 characters of kana and 25 modifications thereof by addition of dots or circles. Among these, there are five pairs of homophonous kana, besides the five which have dual sounds. This makes the number of different sounds which may be written with kana 68. Use is also made of two kinds of repeating signs and one prolonging sign but these have no relation to sounds of kana.
