Different academic fields use different words to mean variants of the same thing. I spent some time trying to disentangle the various words used to mean hypothesis, conclusion, or assumption.
Scientific Method
Theory
- stuff
Hypothesis
- a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
Logic
Conjecture
- an opinion or conclusion formed on the basis of incomplete information.
Postulate
- to claim or assume the existence or truth of, especially as a basis for reasoning or arguing.
Supposition
- an uncertain belief
Proposition
- a statement or assertion that expresses a judgment or opinion.
Math
Theorem
- stuff
Corollary
- a proposition that follows from (and is often appended to) one already proved
Lemma
- stuff
Axiom
- a statement or proposition which is regarded as being established, accepted, or self-evidently true.
- a statement or proposition on which an abstractly defined structure is based.
Assumption
- An assumption is a statement which is introduced into an argument, whose truth value is (temporarily) accepted as True.
- An assumption is unstated information that must be true for the logic of the argument to work. Simply expressed, an assumption is something that the argument assumes while coming to a conclusion
