Did you know?

Redundancy, closely related to redound, has stayed close to the original meaning of "overflow" or "more than necessary". Avoiding redundancy is one of the prime rules of good writing. ""In the modern world of today" contains a redundancy; so does "He died of fatal wounds" and "For the mutual benefit of both parties". But redundancy doesn't just occur in language. "Data redundancy" means keeping the same computer data in more than one place as a safety measure, and a backup system in an airplane may provide redundancy, again for the sake of safety.
