n. (linguistics) excessive repetition of information in communication
Derived from Latin redundantia ("overflowing"), itself from redundare ("to overflow, abound"). The root und (from Latin unda, "wave") suggests a sense of excess or surplus, metaphorically extended to unnecessary repetition. The prefix re- intensifies this notion of overflowing or excess. Over time, the term evolved from literal overflowing to abstract redundancy in language, employment, and technology.
