In common use, the word "supposition" and the word "assumption" may be used, for the most part, interchangeably, with the word "assumption" being the more commonly used and understood word. However, there are some words of caution that must accompany the use of the word "assumption" - far more so than "supposition."
Supposition comes from latin "suppositio" which means "to place beneath.
"Assumption is from "assumptio" which means "taking up."This indicates that the word "assumption" is a more powerful, emotional, word. If I "assume" something, this means that I have "taken it up" and am in complete agreement with the postulate. Furthermore, I have done so without necessarily having explored, completely, all the facts that may or may not make the assumption true. An assumption is, therefore, another word for "unfounded belief." The very word "Assume" conveys this meaning and it has been adopted as such in the common vernacular.
Alternatively, the word "supposition" bears no such negative connotation, and by stating that your belief is a supposition, you are acknowledging that it may be partially formed, and that you are open to further suggestions regarding its value.
