What is presumptive definition?

Presumptive definition refers to a definition that is based on probability or assumptions rather than definitive evidence. In other words, it is a definition that is inferred or deduced from available information, rather than being known with absolute certainty. Presumptive definitions are often used in fields such as law and medicine, where conclusive evidence may be difficult to obtain. They are also commonly used in everyday language, where they can help to convey a general understanding of a concept or idea, even if the specifics are not fully known or agreed upon. It is important to note, however, that presumptive definitions are not always reliable or accurate, and should be verified with additional evidence whenever possible.
