Explanation
In Charles S. Peirce's semiotics, a rheme is a sign representing a qualitative possibility or open predication without asserting it as fact. It resembles a concept or predicate with an unfilled position: it may apply to something but does not by itself say that it actually does. The category is not tied to one part of speech; an image or complex expression may also function rhematically. The conceptual movement separates represented quality from assertion, keeps the referential position open, and asks how combination with further signs transforms the rheme into a proposition.
Movement of thought
1. The sign is tested for whether it offers a possible quality or relation. 2. Open positions for objects or participants are made explicit. 3. The analysis asks whether there is already a truth claim or only possible applicability. 4. Combination with identifying signs reveals the transition to a complete proposition. 5. Alternative semiotic media test whether the function extends beyond parts of speech.
Scientific use case
Semiotics, logic, image theory, and concept research use the rheme to analyse different sign functions. Responsible application must state Peirce's categories and avoid simply equating rheme with grammatical predicate.
Example
The expression “is transparent” opens a property position without specifying what fills it. Only combination with “this glass” produces a statement that can be evaluated as true or false.
Counterexample
A complete declarative is not merely a rheme when it asserts a relation as actual and can be true or false. Nor is an unintelligible fragment automatically rhematic; it must represent a determinable possibility or quality.
Distinction
Distinguish the semiotic rheme from rheme in information structure, from grammatical predicate, and from the dicent. Here it means Peirce's sign type of possible predication without assertion of actuality.
Effect on thought and perception
Rhematic signs open possibilities without fixing them as facts. They provide qualitative materials for description, classification, and imagination while keeping the transition from concept to assertion visible.
Resonance
A property hovers as possibility, still without bearer or factual claim. Connection with an object turns open sense into a determinate statement.

Historical background
In the 1903 Syllabus, Peirce discusses the rhematic symbol as a general term. It makes a possible character available without yet asserting its application to a particular object.
How conceptual history changes the analysis
Separate a property available for predication from an assertion applying it. This Peircean sense must not be conflated with “rheme” as the informative part of a topic–comment structure.
Additional example
Original example: An empty sorting field labelled “fragile” supplies a possible category. Assigning a particular bowl makes a further move. Countercheck: A complete assertion about that bowl is not just the isolated term.
