Alphabet Sets, Vowels, Consonants, and Case Explained
The English alphabet has 26 letters.
Vowels are commonly A, E, I, O, and U.
Consonants are the remaining English letters.
Y can sometimes act like a vowel, so add it manually in custom mode if needed.
Uppercase and lowercase change display, not the underlying random choice.
Custom sets are useful for games, spelling practice, and controlled random draws.
