ｷﾀ━━━(ﾟ∀ﾟ)━━━!!

I've heard that in my language, French, the letters "oi" used to be pronounced as "wé" rather than as "wa", which feels like a funny way to speak French ("L'État, c'est moué!"(although it's unclear wether or not Louis XIV actually said that)). So it's my favourite historical sound change due to it being the only one I can think about.

If I remember correctly, the pronunciation of ふ is also an example of debuccalization. In Early Middle Japanese, what is /h/ in Modern Japanese was pronounced /p/. /p/ then lenited (softened) to /f/, which then debuccalized to /h/ everywhere except before /ɯ/, which is why ふ (/fɯ/) is still pronounced with an oral consonant.

In Japanese compound words, there is a rule known as rendaku, which is the voicing of the initial consonants in the second element of the compound word. For instance, the /k/ in 心 (/ko.ko.ɾo/) becomes a /g/ in the compound 女心 (/on.na.go.ko.ɾo/). In words that begin with an initial /h/ such as 人 (/hi.to/), rendaku does not change it to its proper voiced equivalent, which would be /ɦ/, but instead to /b/. An example is 人々 (hi.to.bi.to). This shows us that what is /h/ now historically acted as /p/, because /b/ is in fact the voiced equivalent of /p/.

one of my favorite things is how Latin evolved to become the romance languages, though French is far beyond any knowledge I have. Certainly, it's the most innovative romance language. I believe Sardinian is the most conservative, the least changed from Latin.

French orthography is beautiful~ English too. And with Chinese, I think these 3 are more beautiful when written, than spoken. If this makes any sense to any1...

spanish shifting the letter h from pronounced like the h in english to silent
also shifting the sound of j from [ʒ] to [x]
that's the only sound shift i remember reading besides the great vowel shift in english but that's too complicated (;´Д`)
