Who discovered vowels?

It's impossible to say who "discovered" vowels, as the concept of vowels has been around since the earliest forms of writing.

Here's why:

* Vowels are fundamental to speech: Humans naturally use vowels to create sounds. Recognizing and understanding these sounds is inherent to language.

* Early writing systems: Many ancient writing systems, like cuneiform and hieroglyphics, only represented consonants. This doesn't mean they didn't understand vowels, just that they chose to focus on consonants in their writing.

* Evolution of writing: Over time, writing systems evolved to include vowels. The Greek alphabet is credited with being the first to use symbols for both consonants and vowels.

So, while we can't point to a single person who "discovered" vowels, the development of vowel representation in writing was a gradual process driven by the need for more nuanced and precise language expression.
