>>24533358>yes but why the letter J shifted while all other letters are phonetically pronounced the same?The Romance languages experienced other sound changes than that in the process of evolving from Latin. For example, V originally stood for what we write in modern English as W, as you might guess by the fact that U and V were originally the same letter.
>What made everyone sperg out over only this one letter in the alphabet?I don't think it's that unique. For example, C is always a K sound in the Celtic languages, in the Slavic languages it's always a TS sound (which comes from the sound it shifted to before I and E in late Latin), and in English and most Romance languages it's a K sound before A, O, and U, and an S, TS, or CH sound before E and I. (Because in late Latin it shifted to TS before the vowels pronounced at the front of the mouth- probably at some point in between it had a sound like Hungarian TY, with the tongue fully obstructing the air but in the place you'd put it to make a Y sound.)
>If the letter H and Y existed why don't Spanish use those for their intended purposeAs for H: Because the H sound had completely dropped in late Latin, so to Romance speakers it had no sound. (Also, Spanish J isn't exactly an H sound, it's like the CH in Bach or loch.)
As for Y: It's funny you should say "intended purpose", because originally the letter Y didn't exist in Latin, it was borrowed from the Greek alphabet, its purpose being to write a Greek vowel sound that Latin didn't have (something like modern German Ü or modern French U). The reason that Romance speakers repurposed it to write the sound it now writes is because, consonantal I (i.e. J) having shifted to make the sound that J makes today, they needed another letter to write semivowel I. Since the Greek Y vowel sound was only ever really present in educated Roman speech, for Romance speakers it just stood for the same sound as I, but wasn't associated with a J sound when used as a consonant, so they used it to write the semivowel sound.
>and stop saying things like "jajajajaja"And why should they? They say it that way because that's the natural outcome of that sound in their language. Are you going to complain that English uses its vowel letters funny relative to other languages now, too? (Which is because of the Great Vowel Shift.)
