The word is logically structured: the prefix 'un-' negates, the stem comes from 'Fehler' (mistake/error), and the ending '-bar' means 'capable of' or 'possible'. 'Unfehlbar' therefore literally means 'not capable of making a mistake'.

In everyday language, 'unfehlbar' (infallible) is often used in an exaggerated or ironic way to express that someone or something is, after all, not perfect. The emphasis and the context make the irony clear.
