From Wikinormous

Information is the outward expression or propagation of an inner thought in the form of an image, a talk, a book or these very letters written here. The perception and understanding of these letters and sentences, the 'between the lines', we could say is the exformation. But since 'ex' means outward, quite like above 'outward expression' and 'in' or 'im' suggests inward, maybe the two have been mixed up?
