Anticipatory completion, also called collaborative completion or co-participant completion, is a practice whereby one participant completes a not-yet-complete turn-constructional unit (TCU) begun by another participant. An example is found in line 2 of the following case, taken from Lerner (1991):

(Lerner 1991: 445)

01  RIC:    if you bring it intuh them
02  CAR: -> ih don’t cost yuh nothing

In anticipatory completion, the second speaker’s utterance begins before the first speaker’s TCU reaches a transition-relevance place (TRP). This feature distinguishes anticipatory completion from the practice of “other-continuation” (Sidnell 2012), where the second speaker adds a syntactic continuation to the first speaker’s turn that has already been brought to possible completion and which has thus reached a TRP.

Various kinds of resources have been shown to furnish opportunities for anticipatory completion.

  • the morpho-syntactic structure of an unfolding TCU, such as multi-clausal compound structures (e.g., the if X, then Y structure observed in the excerpt above), constituent order within a phrase or a clause (e.g., [modifier + head], SVO, etc.), inflectional information provided by morphological affixation present in the TCU-so-far, and so on (Bolden 2003; Hayashi 2003; Helasvuo 2004; Lerner 1987, 1991; Lerner & Takagi 1999; Ono & Thompson 1996; Szczepek 2000a)
  • disruptions in the progressivity of an unfolding TCU, such as intra-TCU silences, word repetitions, word cut-offs, laugh tokens, and so on, which provide “unprojected opportunities” for anticipatory completion (Bolden 2003; Hayashi 2003; Lerner 1996a)
  • local configurations of talk in the immediate sequential context, such as contrast structure, list construction, and other recognizable courses of action like [state description + account] (Hayashi 2003; Lerner 1987, 1991)
  • embodied conduct, such as gaze and a variety of manual/facial gestures (Bolden 2003; Hayashi 2003; Iwasaki 2009).

By anticipatorily completing the first speaker’s TCU-in-progress, the second speaker can accomplish a range of interactional tasks (Bolden, et al. 2019; Hayashi 2003; Lerner 1987, 1996b; Lerner & Takagi 1999; Szczepek 2000b). These include:

  • displaying an understanding of what the first speaker was going to say (without necessarily showing agreement with the first speaker)
  • showing agreement/affiliation with what is being said in the first speaker’s turn
  • demonstrating possession of independent knowledge
  • teaming up with the first speaker in explaining something to a third party
  • converting an imminent dispreferred action (e.g., other-correction, disagreement) into a preferred counterpart (e.g., self-correction, agreement)
  • heckling or otherwise subverting the action being implemented by the first speaker’s TCU-in-progress

When an anticipatory completion is addressed to the first speaker (as opposed to a third party), it is regularly responded to by the first speaker with an acceptance or a rejection of the proposed completion (Antaki, et al. 1996; Lerner 2004). In other words, an anticipatory completion initiates a sequence (the “collaborative turn sequence;” Lerner 2004) in which the first speaker is given a receipt slot to ratify (or reject) the second speaker’s completion as an adequate rendition of the TCU that they were about to voice.
