changes or transtion relevance places. Thus, the objectives of this study are to describe the applicability of adjacency pairs, turn-taking Sacks, Schegloff and Jefferson 1974,
and the applicability of completion points grammatical, intonational, and semantic as in the TB conversations . Specifically, the objectives are :
1 to examine the structures of adjacency pairs in TB conversations.
2 to examine how the end of turn, grammatically, intonationnally, and
semantically are projected. 3
to discuss how the turn-taking of TB conversations operates.
1.4 The Significance of Research
Examining adjacency pairs and turn-taking in the TB conversation is benificial in two respects. First, we can recognize how the first pair part as component of
adjacency pair varies in the TB conversations. For Example, is greeting in Toba Batak always followed by greeting? Secondly, one can describe how the turn taking system
in Toba Batak operate can be understood by examining the turn distribution component. For example, does the current speaker select the next speaker, or the next
speaker applies the self select or the current speaker continues? Analyzing the linguistic properties that can influence the interaction in the TB
conversation can construct the relation between language and interaction ; grammatical, intonational, and semantic can project the end of a turn, so makes it
possible to make speaker changes.

Practically the research findings can be made as a reference for teachers who teach English conversation to homogenous students like that of Toba Batak.
1.5 The Scope of Research
As has been stated in the previous section, this study is examining the interaction structures of Toba Batak conversation and the linguistic structures that
influence the interaction in the TB conversation. The interaction structures in this study can be limited to adjacency pairs and
turn-taking. In adjacency pairs, two parts will be analyzed as their components, the first pair part and the second pair part. In English, there is a greeting in the first part
and also greeting in the second pairs part like in : A : Morning
B : Morning Preferences is also a part of adjacency pair which are shown in invitation. The
response of invitation can be positive as reffering to preference and negative as referring to dispreferences. So first pair part , second pair part, and preference would
be under discussion in adjacency pair. The component of turn-taking such as, turn construction units, turn distribution
component, silence, overlapping talk, and repair are analyzed in Toba Batak Conversation. Here, it will be examinined to what extent turn-taking proposed by
Sacks, Schegloff, and Jefferson 1974 are applicable to the different phenomena such as in Toba Batak Conversation.

The elements of linguistic structure to be examined are grammatical, intonational, and semantic units, as those which are realized in grammatical,
intonational, and semantic completion point related to transition relevance place in turn-taking. So, the turn constructional unit is not included in interactional structure.
