How do you break up the alphabet into 3 groups?

One way to break up the alphabet into three groups is by dividing it into sections based on their positions: Group 1 could include A-I, Group 2 could consist of J-R, and Group 3 could encompass S-Z. Another approach is to categorize them by vowels and consonants: Group 1 for vowels (A, E, I, O, U), Group 2 for common consonants (B, C, D, F, G, H, J, K, L, M, N), and Group 3 for the remaining consonants (P, Q, R, S, T, V, W, X, Y, Z).
