Why is the topic marker wa spelled ha?


I would like to know why the topic marker wa is spelled は instead of わ。

Also, is this the only misspelled particle in Japanese (or anything resembling
a particle or other figure of speech component), or are there also other
instances?

Thanks.




That is a long story but to keep it short I would say that the language
changed many times, and at some point the writing system for
"ha/は","wo/を","he/へ" changed for "wa/わ", "o/お", "e/え", but just for the
particles they kept the original writing system while still changing the way
it is pronounced.
