Etymology
The word 'unerring' is built upon the Latin verb errare, which originally meant "to wander" or "to stray," a sense that evolved metaphorically into "to make a mistake." The Germanic negative prefix un- is attached to the root, creating the sense of "not erring." The adjectival suffix -ing transforms the verbal action into a permanent quality. Thus, the literal construction "not wandering/mistaking" elegantly conveys the modern abstract meaning of being consistently accurate and faultless.
