checking wether an input is using letters of the alphabet

afternoon forums.

I need to get a way of testing as to wether an inputed character is part of the english alphabet.

i have come up with the following code but its not working at all.

Code:

 
until [ (echo $in1) = '[a-z]']
       do
       echo This is not a Letter
       done

any help would be beneficial to me.
