Roque Ferriols’s Pambungad sa Metapisika is the first book of metaphysics thoroughly written in Filipino. This paper studies the basic terms (batayang kataga) of Ferriols’s metaphysics. It suggests a meeting between Aristotle’s omonimo, sinonimo, and paronimo, on the one hand, and Ferriols’s use of scholastic terms univoco, equivoco, and analogum, on the other. It points out the limitations of univoco and equivoco and suggests a way of presenting the relationship between equivocum and metaphora. It concludes that the language of metaphysics is analogum. The last section reflects on silence as a component of metaphysical language.
