>>10411989Nearly all languages use more than 5 vowels, and there not being a unique letter for each vowel isn't uncommon either. Making a unique symbol for every single way A can be pronounced isn't practical for a multitude of reasons.
The real issue with english is that the standard way of pronouncing the letters A,I,O,U in English aren't even vowels. and although the english "E" is a vowel the way the english pronounce it is how every other language that uses the latin alphabet uses the letter I.
Seriously the great vowel shift is the bane of my existance. Fuck that shit.
