In discourse, a premise (also "premiss" in British usage) is a claim which is part of a reason or objection. It is a statement presumed true within the context of the discourse for the purposes of arguing to a conclusion. Premises are sometimes stated explicitly by way of disambiguation or for emphasis, but more often they are left tacitly understood as being obvious or self-evident ("it goes without saying"), or not conducive to succinct discourse. The accuracy or truth of the conclusion depends on both the truth of the premises and the soundness of the reasoning from the premises to the conclusion.
