I’ve been looking at onyomi kanji and noticing some patterns.
A lot of the “h” sound in ancient Chinese has turned into “k” in Japanese. Thats not a mystery. Suggests the ancient Chinese “h” must’ve been really hard.
And the “b” and “p” sounds have turned into the “h” sound. Anyone know why this is so? Are there precedents for p/b>h in any other languages?
