Unspoken → It is formed from "un-" (meaning not) and "speak" (from Old English "specan", meaning to say or talk). The word "unspoken" refers to something that has not been said or expressed verbally.
Think of something that is 'not' ('un-') 'said' ('speak') — that's why unspoken means something that hasn't been verbally expressed.
