Abstract:

Redundancy is widely seen as a kind of linguistic cholesterol, clogging the arteries of our prose and impeding the efficient circulation of knowledge. However, I will argue that, just as a more thorough understanding of cholesterol reveals the existence of good cholesterol (HDL) as well as bad (LDL), so a broader view on the principle of redundancy reveals its effectiveness in certain situations, particularly beyond the sentence level. In this article I aim to revive the beneficial or functional sense of redundancy and show that functional redundancy in writing need not be a contradiction in terms. I believe a discussion of redundancy should include its opposite, ellipsis, so I will define both terms, emphasizing the beneficial sense of each, and then show how they appear in both reading and writing. In the latter part of the article, to illustrate the pervasiveness of redundancy and ellipsis, I will discuss examples of each in document design and in figures of speech. My attention will mainly be on technical writing, but the principles I will discuss may apply to other genres, too.
