I'm confused. According to Wikipedia "A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon." The same article also states that "In common usage in the 21st century, a hypothesis refers to a provisional idea whose merit requires evaluation". Thus what I called "hypothesis" is indeed one by Wikipedia's usage. I also quoted the sentence "For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it." (my emphasis) in order to point out that what pbhjpbhj called "hypothesis" seems to be normally called "scientific hypothesis".
