What do vowels mean?

Vowel letters, or vowel letters, refer to letters that play a sound role in language. Vowels are also called "vowels".

Vowels refer to sounds that are not hindered by the vocal organs, and consonants refer to sounds that are hindered by the vocal organs.

In Latin alphabet, A, E, I, O and U are usually vowels. But the specific definition is still based on the definitions of various languages. For example, in Welsh, w and y are also vowels.

Czech uses r to represent the vowel of one of the rolling tongues, so in Czech, "r" is also a vowel letter. In addition, there are two special vowels in many languages in the Indian subcontinent: vowel R and vowel L.
