Answer:
What is a five-letter word that has brain in it?
What has to be broken before it can be used?
Forward Iβm heavy, but backwards Iβm not.
There are two meanings to me. With one I may need to be broken, with the other I hold on. My favorite characteristic is my charming dimple.
I can be written, I can be spoken, I can be exposed, I can be broken.
If itβs information you seek, come and see me. If itβs pairs of letters you need, I have consecutively three. What am I?
