What does it mean for something to be "redundant"?

The term "redundant" refers to something that is characterized by unnecessary repetition. In the context of language or communication, redundancy often implies that certain elements are repeated in a way that does not contribute additional meaning or value. For example, phrases that repeat the same idea using different words can be viewed as redundant because the original message remains clear without the added repetition.

Choosing the first option reflects this understanding well, as it directly addresses the idea that redundancy involves repetition that is not essential to comprehension. This concept is often discussed in writing and speaking, as conciseness is typically valued for clear communication. The other options, while addressing different aspects of language, do not capture the essence of redundancy, which specifically involves unnecessary repetition.
