A pre-expansion (sequence) (also known as a pre-sequence, or just pre) is a sequence type that expands base adjacency pairs prior to their first-pair part (henceforth: 'FPP'). Since such pre-expansions are themselves usually organized as adjacency pairs, they are commonly referred to as pre-sequences (Sacks 1992: 685; Schegloff 1990: 60, 2007: 28).

By projecting a following action, pre-sequences do not only precede other sequences in terms of temporality, but are – as Schegloff (2007: 28) put it – “recognizably ‘pre-,’ that is, preliminary to something else.” A central feature of such pre-sequences is “to help the interaction avoid a sequence with a rejected base FPP” (Schegloff 2007: 31).

Depending on the specificity of the action projection, a distinction is made between 'generic' and 'type-specific' pre-sequences. Generic pre-sequences such as summonses or other attention-getting devices do not project a particular type of action (Schegloff 1990: 60, 2007: 48–53). In their “non-terminal” (Schegloff 1968: 1081) character, they foreshadow that there is an action to follow, though they do not specify what kind of action that will be. Type-specific pre-sequences, in contrast, project specific subsequent actions, such as offers, invitations or announcements (Schegloff 1990: 60). However, as Schegloff points out, it is important to note that the turn design of a FPPpre does not ‘automatically’ allow for a clear assignment as pre-invitation, pre-request, or the like, by its recipient on its occurrence (see Schegloff’s 2006: 150–152 remarks on “possibles” in this context). Although type-specific pre’s “commonly project” or “are regularly preliminary” to a specific base sequence (Schegloff 2007: 29), their recipients “may have to entertain the full range of possibilities momentarily, using the immediately following talk to find out what sort of sequence is in progress” (Schegloff 2006: 152).

An example of a type-specific pre-sequence, a pre-invitation, can be found in the following extract from Schegloff (2007: 30):

(Schegloff 2007: 30)

01  CLA:            Hello
02  NEL:            Hi.
03  CLA:            Hi.
04  NEL:  FPPpre->  Whatcha doin’.  
05  CLA:  SPPpre->  Not much.      
06  NEL:  FPPb->    Y’wanna drink?
07  CLA:  SPPb->    Yeah.  
08  NEL:            Okay.

As the example illustrates, the key function of the pre-invitation is to avoid a rejection of the impending invitation (Sacks 1992: 685–686, Schegloff 1980: 113-114, 2007: 31). In the case where the second-pair part of the pre-sequence (SPPpre) facilitates the continuation of the projected main action (as in the above extract), it is called a go-ahead (Schegloff 2007: 30). If it discourages the other speaker to proceed with the projected action, it is referred to as a blocking response (Schegloff 2007: 30).

Similar functions of checking “that there are grounds for starting some yet-to-come main action” (Sorjonen 2002: 176) have also been described for pre-announcements (e.g., Maynard& Frankel 2006; Terasaki 2004 [1976]), pre-requests (e.g., Levinson 1983; Rossi 2015), pre-closings (Schegloff & Sacks 1973: 303-305), or pre-offers (e.g., Schegloff 2007: 34-37). The core feature of pre-sequences, namely “to help prospective speakers of base first-pair parts avoid rejection” (Schegloff 2007: 131), is also discussed in relation to face-work, as it allows one to avert dispreferred reactions (Lerner 1996).

While the term ‘pre-‘ is widely used in interaction research, more recent contributions on the sequential structures of requests have critically questioned whether the distinction between pre-requests and requests is always pertinent from an interactional perspective (Fox 2015: 43–44; Lindström 2005: 212; Walker 2013: 457). Drawing on examples from Levinson (1983: 361–364), in which customers ask about the availability of a product and the salesperson hands it to them in the very next turn, it is argued that the notion of “pre-request” is not entirely accurate to characterize these customer inquiries because the salesperson treats them retrospectively as actual requests and not as something preliminary to those (Lindström 2005: 212–214).
