There's a word I love in French, it is composed of three vowels which have their own pronunciation. Nonetheless, somehow when combined they make another sound...which is actually the name of another vowel that is actually pronunced the same way lol.
The word is EAU, pronunced as [o], the letter O is pronunced as [o].
E -->[e] A -->[a] U --> [y]
