When it comes to describing something that's characterized by redundancy, there are many different synonyms you can use to get your point across. Phrases like "repetitive," "superfluous," and "reiterative" all fit the bill, as do words like "verbose," "wordy," and "redundant" themselves. If you're looking for a more nuanced way to describe this kind of quality, you might opt for descriptors like "circular," "incestuous," or "self-referential," all of which speak to the way in which redundant elements often reinforce each other in a closed system. Whatever your chosen phrasing, emphasizing the repetitive nature of something can be a powerful way to draw attention to the need for brevity and precision.
