Explanation
A conversational turn unit is a contribution that participants can recognise as possibly complete for its current speaker. Grammar, prosody, action, and context jointly indicate whether continuation remains projected or a transition-relevant place has been reached. Such a unit may consist of one word, a sentence, or several coupled components and may be extended or repaired during production. It is not identical with an orthographic sentence and should not simply be equated with the speaker's entire turn, which may contain several possible completion points. The concept reveals conversation as temporally coordinated construction. Participants do not wait for finished texts; they continuously project structure and action and place their own talk where another contribution has become sufficiently complete.
Movement of thought
1. One person first begins a contribution whose grammar, prosody, and social action unfold only through time. 2. Other participants project possible continuations and recognise which components remain necessary for a request, assertion, answer, or story. 3. At a possible completion, syntactic, prosodic, and pragmatic cues converge upon a place where speaker transition becomes relevant. 4. A counter-test examines recognisable completeness and sequential treatment and separates the unit from sentence, breath group, entire turn, and arbitrary pause. 5. The contribution returns through others' response as complete or retrospectively extended; uptake confirms or revises its boundary.
Scientific use case
Conversation analysis, interactional linguistics, and prosody research annotate possible completion, transition places, overlap, and extension in audio and video. Boundaries are evidenced through participant orientation.
Example
Someone answers immediately after “And tomorrow?” because grammar, falling intonation, and context made the two words recognisable as a complete follow-up question.
Counterexample
A speaker audibly breathes in the middle of an incomplete noun phrase. The pause alone does not make the fragment a possibly complete conversational contribution.
Distinction
Distinguish it from the entire turn, turn-constructional unit as a technical analytic category, sentence, utterance, intonation phrase, speaker change, sequence, repair, and speech pause alone.
Effect on thought and perception
Conversational units enable finely timed speaker transition, distribute action into manageable parts, and show grammar and prosody emerging together in real-time dialogue.
Resonance
A contribution stretches word by word; at a possible ending, a brief space opens into which another voice may enter.

Historical background
Sacks, Schegloff and Jefferson’s 1974 model made turn-taking organization foundational to conversation analysis. It treats conversational allocation as locally managed, party administered, interactionally controlled and sensitive to recipient design. Turns are built from turn-constructional units, whose possible completion creates transition-relevance places at which ordered speaker-selection rules apply. A conversational turn is therefore not identical with a grammatical sentence, and not every pause completes one. The English analytical tradition is directly supported; the history and exact scope of the German label Gesprächsschritt remain unestablished.
How conceptual history changes the analysis
A conversational turn must be identified through possible completion and sequential relevance. Sentence boundary, breath and speaker change must not be treated as automatically identical.
Further explanation
A turn is not a fixed sentence-sized container. Possible completion and speaker selection matter, requiring syntax, pauses and actual uptake to be considered together.
The Atlas moves from individual utterance production towards joint organisation. A brief item may complete an answer, while a full sentence may belong to a continuing contribution. Not every silence invites another speaker. This offers practical attention to an interlocutor without promising a mechanical rulebook for conversation.
Additional example
Original example: “Yes” can complete an answer; “I have three reasons” can launch a longer turn. Word count alone does not identify its boundary.
