Why is the Hiragana ‘mi’ so similar to the Devanagri ‘ma’?
I’ve always been bothered with that question. The similarity is unmistakable, but I fail to see any connection. The katakana mi isn’t similar to the hiragana mi, why should the hiragana mi develop such an unusually strong resemblance to the devanagri ma?
A look at the history of Hiragana shows that the alphabet originated from the Chinese man’yōgana. Here’s a table showing the evolution of the man’yōgana to the hiragana, sourced from Wikipedia:
This appears to hint that there is no connection between the devanagri ma and the hiragana mi, as the man’yōgana mi looks vastly different from either of the two letters.
I suppose the only answer left is coincidence.
