In plain English: Something is redundant when it repeats itself unnecessarily and adds no new value.

Usage: Use redundant to describe information that repeats something already stated or an item that serves no useful purpose because it exceeds necessity. Avoid confusing this adjective with the noun redundancy when referring specifically to job losses caused by excess staff.
The word redundant comes from the Latin verb redundare, which originally meant "to flow over" or "to spill." It entered English with this sense of overflowing before evolving to describe something that is unnecessary because it repeats what has already been said.
