Related: Pronoun-antecedent agreement, Verb tense consistency

Related: Dangling modifier, Pronoun-antecedent agreement

A statement offered as evidence or a reason inside an argument. Premises are the support that is supposed to justify accepting the argument's conclusion.

Reasoning that moves from general rules to a specific conclusion. When the premises are true and the logic is valid, the conclusion must be true.
