I have split the alphabet into two sets using a rule:

  • A E F H I L M N O R S X
  • B C D G J K P Q T U V W Y Z

What is the rule?

  • $\begingroup$ @JulianRosen Doesn't look like a duplicate, as mine has a different division rule. $\endgroup$

    $\begingroup$ The linked puzzle has a list of 14 divisions, yours is number 10 on the list. $\endgroup$ Mar 8, 2016 at 20:18
  • $\begingroup$ Hm, I didn't see that. Should I remove this question? $\endgroup$

  • $\begingroup$ Don't remove this question. Leaving duplicates is better, makes it easier for people to find the first version. Plus there's an answer here already $\endgroup$ Mar 8, 2016 at 21:46

1 Answer 1


The rule is

The top set when spelled would start with a vowel and the bottom set would start with a consonant. For example x would be spelled ex(vowel) and z would be spelled zee(consonant)
