Many of the topics and concerns which preoccupy applied linguists intersect andare shaped by these aspects of the organization of interaction. The remainder of thissection will sketch several of these areas, and suggest their potential bearing on appliedlinguistic interests. Ensuing sections start from the applied linguistic end and touch onwork which has drawn on conversation analytic resources.
It is worthwhile to underscore a single underlying premise of this work whichshould be relevant to applied linguists as well. People use language and concomitantforms of conduct to do things, not only to transmit inf
rmation; their talk andother conducts do things, and are taken as doing things such as requesting, offering,complaining, inviting, asking, telling, correcting, and other actions which talk-in-interaction can accomplish.
By "actions" we are not referring to physical actions but to somethingaccomplished through the talk, and we are referring not only to actions with familiarvernacular names like those just mentioned, but recognizable and describable actionswithout such names （such as confirming allusions）. Understanding analytically whatactions are being done by some unit of talk is not accessible to casual inspection andlabeling. It requires examination of actual specimens of naturally occurring talk-in-interaction and analysis of what they are designed to accomplish by their speakers andare understood to have accomplished by their recipients, and what practices implementthat design.
On the one hand, the practices of talking in interaction are grounded jointly in
Idealing with the contingencies of managing to sustain talking together as an orderlyarena of action, and
n the other hand, the contingencies of producing and recognizingdeterminate actions, combinations of actions and sequences of actions. For those tryingto understand a bit of talk, the key questions are: why and what is getting done byvirtue of that conduct, done that way, in just that place？ This is the central issue for theparties to the talk- for its construction and understanding.
