Unsay → It is formed from "un-" (meaning not) and "say" (from Old English "secgan", meaning to speak). The word "unsay" means to take back or retract something that has been said.
Think of 'not' ('un-') and 'speak' ('say') — so unsay means to not speak something anymore or to take back what was said.
