The answer to the riddle is "FAN." "Moving air" refers to a device used to create a current of air, and "4 letters" means that the answer is a four-letter word. If you take the letters "d," "i," "l," and "d" and rearrange them, you can form the word "DI[D]L." However, this is a red herring, and the actual answer is "FAN."
