Topic and Comment¶
An information-structure organization in which a comment predication is assessed relative to an aboutness topic in an utterance.
Core Idea¶
Topic and comment names a way an utterance organizes information.[1][2] The topic is what the speaker presents it as being about; the comment is what is predicated and assessed relative to that topic.[1][2] These are roles in an interpretation, not a rule that the first words must name the topic.[1][2] A topic can be supplied by earlier discourse or the situation even when no word in the current utterance expresses it.[1]
An assignment needs evidence. A preceding question may make one participant the aboutness target; a language may also mark a topic grammatically.[1][2] The same visible words need not carry the same topic assignment in every conversation.[1][2]
Scope of Application¶
This abstraction belongs to linguistic information structure: analyzing how a speaker organizes an utterance for a discourse setting.[1][2] English question and intonation evidence and Tsez topic morphology are different ways to support an analysis.[1][2] Neither is a universal required form.[1][2]
The entry uses a bounded aboutness-and-predication analysis. Other theories divide information into focus/background or given/new in ways that need not match topic/comment exactly.[1][3]
Clarity¶
Ask what is being discussed and what is said about it. Do not simply take the grammatical subject, first phrase, or topic particle as a complete answer. In Polinsky and Potsdam's Tsez example, the snake is topic-marked while the boy is the grammatical subject.[2] A marker helps identify a role, but the utterance and interpretation supply the full organization.
Manages Complexity¶
An utterance can have syntax, word order, intonation, discourse history, and information status at once. Topic-comment analysis keeps the aboutness assignment distinct from these other dimensions. The English case shows a change in interpretation with the words held fixed; the Tsez case shows one marked topic across two word orders.[1][2]
Abstract Reasoning¶
Treat the assignment as a testable analysis of a particular utterance. Identify the topic, the predication assessed relative to it, and the contextual or grammatical evidence. If the preceding question changes, ask whether the topic changes. If word order changes while a topic marker remains, ask whether initial position was really required. Neither test alone proves a rule for every language.
Knowledge Transfer¶
The transferable question within linguistics is: which referent is the utterance about, and what is predicated of it? The answer may come from context, prosody, morphology, or their combination. A report or website can have a topic in an everyday sense, but that analogy does not itself instantiate the linguistic relation.
Examples¶
English prior question. Gundel, Hedberg and Zacharski discuss “Anna came with Manny.”[1] Under a preceding question about Manny, Manny is the topic; under a question about Anna, Anna is the topic.[1] They report different intonation patterns for these readings.[1] Mapped back: the fixed utterance has a context-supported aboutness target and a predication assessed relative to that target.
Tsez marked topic. Polinsky and Potsdam give a clause about a boy killing a snake, with the snake bearing a topic suffix in both a snake-first and boy-first order.[2] Their categorical analysis calls the comment the main predication about the topic.[2] Mapped back: the marked snake is the topic; the killing predication is the comment under their analysis. The source does not provide a separate prior-question vignette for this pair.

Not to Be Confused With¶
A Topic Marker is a linguistic sign that can help express a topic; it is not the entire topic-comment relation. A Discourse Relation connects discourse segments by coherence, whereas this entry assigns roles within an utterance. An “all-comment” utterance need not lack a topic in every framework: Gundel and colleagues allow a contextual topic without overt topic words.[1] This entry is an approved unparented root in the current typed graph because no tested live node supplies a necessary all-instance parent.
