* Vowel: A, E, I, O, U (and sometimes Y).
* Consonant: All other letters of the alphabet.
* Number: Refers to the quantity, or how many of each type of letter there are.
So, a "2 vowels and consonant number" would mean a word (or perhaps a code) that has:
* 2 Vowels: For example, "ai", "eo", "ou", "ee", etc.
* 1 Consonant: For example, "b", "c", "d", "f", etc.
Examples of words that fit this description:
* "eat" (2 vowels: "ea" , 1 consonant: "t")
* "oil" (2 vowels: "oi", 1 consonant: "l")
* "eye" (2 vowels: "ye", 1 consonant: "y")
Important Note: There are many possible combinations of vowels and consonants, and words don't always follow these strict rules. This description is simply a way to categorize certain words or codes.
