What are CVCV domains? and why?

What is CVCV?

C = consonant (a consonant is "a basic speech sound in which the breath is at least partly obstructed")
V = vowel (a vowel is "a speech sound which is produced by comparatively open configuration of the vocal tract, with vibration of the vocal cords but without audible friction""
Note: definitions from the New Oxford Dictionary of English, 1998

In the Latin alphabet, the vowel letters are A, E, I, O, U.
The letter Y can be used to represent different sounds in different words, and can therefore fit either definition (Consonant or Vowel) The letter Y is probably more often used as a vowel, but in this role is often interchangeable with the letter I

By general concensus, there are 13 letters from the 21 Consonant are called Premium Consonant Letters, they are:
B, C, D, F, G, H, L, M, N, P, R, S, T.
The 8 left (J, K, Q, V, W, X, Y, Z) are called non-premium letters

A CVCV Domain is a Domain consisting of 4 letters in CVCV sequence, for example, bade, beco....

Why CVCV Domains?

There are Lots of investors seek words that can be pronounced, CVCV domains often have a catchy sound to them and are quite brandable. They are short, easy to spell, easy to pronounce, and rhymes with itself.

The available CVCV domains are limited

All CVCV.COM are gone, and more than 90% CVCV.NET taken already. Even for the latesr released .MOBI, 40% CVCV.Mobis are registed already (Most still available CVCV.Mobis are with non-premium letters)

There is a total of 15,000 CVCV domains only (21 consonants, and 6 vowels . Letter Y acts as both consonant and vowel = 21x6x21x6 =15876, then remove the combinations with "YY" included, final number is 15,000). If you look at CVCV Domains with Premiun Consonants only, there are 6084 (= 13*6*13*6) Premium CVCV Domains only for each TLD!!

If you can't afford to invest in generic dictionary dot coms, then invest in CVCV Domains (Editor's Note: well... at least, this is the opinion of some domainers, but be creative and look for other niches as well. Some CVCs are nice, however, and can be brandable. In such a case, don't miss a good opportunity if you come across one, but remember that not all CVCVs will make you rich!)
