Dealign is formed from the prefix "de-" (meaning to reverse or remove) and the root "align" (from Latin "lineare", meaning to line up or arrange). The word means to reverse or remove the arrangement or alignment of something.
Think of 'removing' ('de-') the 'alignment' ('align') of something — that's what dealign means.
