A logical syllogism of the third figure in which the major premise is particular and affirmative, the minor is universal and negative, and the conclusion is particular and negative.
From Medieval Latin, derived from 'festinus' (hasty) combined with syllogistic naming conventions. Medieval logicians named different forms using Latin word patterns to distinguish argument structures.
Medieval logicians named their syllogisms like a secret code—'Festino' sounds like someone rushing, but it's actually describing a very specific way of arranging three logical statements to prove something is false.
