# Difference between “premise” and “assertion”

I was preparing for the GRE exam, and was wondering what the difference was between a premise and an assertion. Any example which highlights the difference would be immensely helpful (something I haven't been able to find online).

-

An assertion is a statement of a fact or belief, while a premise is a statement from which another is inferred. For example, if we use the assumption X to conclude Y, then the premise X has been used to make the assertion Y.

Couldn't you make the assertion that all bananas are yellow? –  Mitch Jun 9 '12 at 16:54
@Mitch You could. Assertions are like conclusions in that they can in turn become premises for further conclusions/assertions. While you could make a baseless assertion that all bananas are yellow, one possible premise could be "every banana I've seen as of yet has been yellow." –  user2512 Jun 9 '12 at 22:00
@JasperLoy: actually I'm being serious. 'All bananas are yellow can be just as much a premise or assertion as 'this banana is yellow'. There is no difference between the two as far as assertion or premise is concerned. –  Mitch Jun 9 '12 at 22:14
@JasperLoy: sure there's a logical connection between the two, but the fact that one implies the other says nothing about their status as an assertion or premise in a particular argument. –  Mitch Jun 9 '12 at 22:29
@JasperLoy: clear in what way? You've paired them, but if you follow what I said , then your pairing is arbitrary and could go the other way. So, can you add any content that would distinguish premise and assertion with your two examples? –  Mitch Jun 9 '12 at 23:38
