conjectural
Based on supposition
Conjectural means based on conjecture—inference without firm proof.
A conjectural explanation is reasoned but unverified: The dating of the manuscript remains conjectural.
The word appears most often in scholarly or investigative contexts where evidence is incomplete and conclusions tentative.
