The word unerring has its roots in the combination of the prefix un- (meaning not) and the word erring. Erring comes from the Middle English word erren, which in turn comes from the Old English word erre, meaning to go astray or to make a mistake. Thus, erring originally referred to making mistakes or going in the wrong direction. When paired with the negating prefix un-, it creates the word unerring meaning not making mistakes or not going astray.
