What does postulatory mean?
Postulatory is a formal adjective meaning relating to a postulate, especially a statement or proposition put forward as an assumption for further examination. In philosophical and mathematical writing, it marks a claim that provides a starting point for an argument or system without necessarily being independently established. A postulatory principle might be accepted provisionally because it organizes later reasoning, but it remains open to confirmation, revision, or rejection. The term is consequently more specific and technical than words such as hypothetical or conjectural. It is commonly encountered in discussions of logic, philosophy, scientific methodology, and the foundations of theoretical systems. Although postulatory claims can occasionally prove to be true, the word describes their role or status within an argument rather than their eventual truth: they are propositions advanced as foundations, not conclusions demonstrated by evidence.

Where does postulatory come from?
The word derives from the Latin postulare, meaning “to ask, demand, or claim,” through the related English noun and verb postulate. The adjective postulatory was formed with the suffix -atory, which expresses relation or connection. The same Latin source also underlies postulation and postulator, and cognates appear in other European languages.
