An "hypothesis" is a tentative explanation for a given set of facts.

Explanation:

An "hypothesis" (plural, "hypotheses") is a proposed explanation for a given set of facts or observations. It is a starting point for scientific enquiry: the "hypothesis" may be right, it may be wrong, but it allows a basis for further experiments that test the correctness of the "hypothesis".
