I am reading through Remembering the Kana and attempting to learn Hiragana. I have been learning Japanese for awhile now, and thought that I had the pronouncication down, however, I have now hit a wall. In the book the hiragana symbol for "Ke" (and in addition to the one for for "He") says that it is pronounced like Ca in cape (and as in Hay).
Is this a typo, or just part of how the Hiragana works? From everything that I have been taught about the pronouncication it should be pronounced as He as in Help, i.e. a eh sound.
If this is correct, then is there a list of differences that I can reference to keep me on track?
