Alright, here is the next set of characters from the hirigana 'alphabet'. *For future reference: both hirigana and katakana 'alphabets' have 46 characters.*
か: kah = ka
き: kee = ki
く: koo = ku
け: keh = ke
こ: koh = ko
If you have begun to notice a 'pattern' in the characters, then you are on track. After the first five 'vowel' characters, all other characters are combinations of 'consonants' and the 'vowels'. Always in the a i u e o order as well. Also, I am/will continue to post all hirigana lessons in order, consecutively.
