Origin: υπόθεσις/hypothesis (=assumption)
υπό/hypo(=under) + θέσις/thesis(=point, proposition) > verb τίθημι/tithimi(=set, put, to place)
Coined: since 1596, from Middle French “hypothese”
An assumption made for the sake of argument
The term "hypothesis" has different meaning from the term "theory" although they often used synonymously. The main difference between a theory and a hypothesis is that theory predicts events in general terms and it is generally accepted while a hypothesis makes a specific prediction that has yet to be tested. One definition of a theory would be that it is an accepted hypothesis.
