Explanation
Semiosis is the process in which something is understood as a sign of something and carried forward in further interpretation. A perceptible vehicle does not refer by itself but within a relation among sign, object, and interpretive effect. The resulting interpretation may itself become a sign for another step. Meaning therefore appears neither as fixed property of a thing nor as arbitrary private invention, but as movement constrained by rules and experience. Different communities may read the same trace differently and correct their interpretations. The concept makes signification visible as temporal, open, yet bounded activity in which reference to the world and further thought arise together.
Movement of thought
1. Something perceptible first appears as a possible trace, form, or action within a situation. 2. An interpreting person or practice relates that appearance to an object or context. 3. The resulting meaning influences expectation and action and may itself become the point of departure for further signs. 4. A counter-test examines material trace, convention, context, and competing readings against arbitrary attribution. 5. The sign returns as a node in an ongoing process whose meaning is tested and altered through further interpretation.
Scientific use case
Semiotics, communication, and cultural research can reconstruct sign chains, interpretants, and contextual change. Experiments can test how convention and experience stabilise or redirect interpretation.
Example
A red sheet on a laboratory door is understood as a warning; the warning prompts a search for a hazard notice whose symbol then elicits a particular protective action.
Counterexample
A physical stimulus is not semiosis when nothing treats it as a sign. Nor is every association an adequate interpretation when context and the sign relation resist it.
Distinction
Distinguish semiosis from sign, meaning, signal response, and mere association. A sign is one relational component; semiosis names the whole process of understanding and continuation.
Effect on thought and perception
Semiosis transforms perceptible things into orienting meaning, connects signs with action, and keeps interpretation open as a continuable and corrigible process.
Resonance
A trace calls forth an interpretation that moves further signs; meaning travels as response through a chain that remains open in principle.

Historical background
For Peirce, semiosis is the action or influence of signs as an irreducibly triadic process: sign, object and interpretant cooperate so that the sign relates to its object and continues in further interpretation. Because an interpretant may itself function as a further sign, semiosis is not a one-time private reaction or a merely dyadic stimulus-response relation. Peirce's terminology and classifications changed across phases of his work. The prepared CP passage supports the triadic formulation, while his Greek historical aside and later uses by Morris were not independently reconstructed here. German Semiose and English semiosis receive the same theoretical tradition.
How conceptual history changes the analysis
Analysis should identify at least the sign-vehicle, object relation and generated interpretant and show how the process may continue. Mere causation between two events is not yet a complete analysis of semiosis.
