How many 3-4 letters words?

[Genialnames]

I am searching for information about how many words exist (in english) of 3 and 4 letters, that have a complete meaning. (exluding abbreviations neither acronyms) like

"two"
"bat"
"nose" etc.

I have read somewhere that a three letter domain worth about 500$ and up undeveloped, just because three letter and because are all taken (so the only way to get one is to buy it from the owner..)

Also I have read that the four letters words will rise their value in short,from the present 50-70$ because are nearly to finish (? today a friend sent to me a list of 50.000 unregistered LLLL. that's a lot)
I think there is al relation with the value and the above question.

Have you some info about that?
rep to those who first post useful information, thanks!

first. 3 letters are worth around 1.2k mininum for the real bad ones and for real words at least 10k.

And yes the LLLL.com available list is shrinking . sadly to say a lot of what is left is made up of crap letters.
