Thanks Robert
However i tried otherway and it seems to work fine. I know my solution 
is not a clean one but it works for my learning.
def SMSdeflater(message)
     msg=message.chomp.downcase
    @smsdictionary.each_pair do
      |key, value|
      tmpvalue = value.chomp.downcase
      msg=msg.sub(tmpvalue,key)
      puts msg
    end
end
