Discourse community
ENG 108, Fall 2014, Bradley Dilger ~ http://dtext.org/
Writing researchers have realized the important role of social interactions in writing by redefining
concepts such as genre along social lines (Carolyn Miller’s notion of genre as “social action”) and by
developing other concepts such as rhetorical situation and ecology. Thomas Deans defines discourse
community (abbreviated here as “DC”) as “a group of people unified by patterns of language use, shared
assumptions, common knowledge, and parallel habits of interpretation.” Researchers commonly use
discourse community to help them identify the contexts which shape writing, and to understand the
connections between language, reading, writing, and social forces.
John Swales (1988, pp. 212–213) is one of the most influential researchers who has defined discourse
community, offering six characteristics which define them:
1. a “communality of interest,” or shared, public goals;
2. mechanisms for intercommunication between members;
3. continual attention to #1 and #2 above — feedback about their form and function;
4. expectations for the roles of texts and the topics texts engage — that is, the features and purposes
of genres;
5. shared and specialized language, such as jargon and inside jokes;
6. enough members with expertise in both content and communication methods to ensure the
operation of the group as a community.
This is admittedly broad, intended to be flexible enough to cover a large range of variations in behavior
and makeup:
•Size. Some are large—we could consider Purdue a discourse community—but very small DCs
exist too—a group of four women who meet monthly for dinner, wine, and conversation. For
analytical purposes, more narrowly defined DCs are often more useful.
•Purpose. Very specific purposes can shape the operation of discourse communities, such as a
city’s desire to support local farmers by hosting a farmers’ market. Or there can be a number of
purposes which shift over time.
•Approach to membership. DCs can be closed or open; they can welcome or push away novices;
they can allow or forbid temporary members. For example, you can go to a flea market and
quickly pick up some of the local customs in order to talk to vendors—and never go back.
•Duration. Discourse communities can be created to meet a specific need and then disperse, like a
college class. Or they can be developed with a much longer duration in mind—as is the case with
many community organizations.
•Key communication forms and genres. Some DCs use speech more than writing; some use
particular forms of writing in particular ways.
•Overlap with other DCs and organizations. Discourse communities can overlap with many
others, and in fact that overlap can be purposeful (consider government organizations intended to
provide oversight of certain industries, like the USDA).
•Formality in makeup. These and other ways DCs are defined and shaped can be very formal,
codified in writing, or they can be “ways we do things” which develop over time—“unwritten
rules” which are no less important.
Not all groups are discourse communities! As Swales and Anne Beaufort (1998, 2007) both observe,
there are many groups which exist without being communities. Interaction between members, involving
some form of specialized communication, is the key. (Again, we define writing broadly, so a group of
