syllogism

/ˈsɪlədʒɪzəm / (say 'siluhjizuhm)

noun
1. Logic an argument with two premises and a conclusion. Both the premises of a categorical syllogism are categorical propositions, containing just three distinct terms between them, e.g. all men are mortal (major premise), Socrates is a man (minor premise), therefore Socrates is mortal (conclusion); at least one premise in a hypothetical syllogism is a hypothetical proposition, e.g. if Smith is eligible to vote he is a citizen (major premise), Smith is eligible to vote (minor premise), therefore Smith is a citizen (conclusion); at least one premise in a disjunctive syllogism is a disjunctive proposition, e.g. either Smith is out of town or he is ill (major premise), Smith is not ill (minor premise), therefore he is out of town (conclusion).
2. deductive reasoning.
{Latin syllogismus, from Greek syllogismosreplacing Middle English silogime, from French}
