Oppositeness, i.e. the relation between opposites or contraries or contradictories, has a fundamental role in human cognition. In the various domains of intellectual and psychological activity we find ordering schemas that are based, in one way or another, on the cognitive figure of oppositeness. It is therefore not surprising that the figure and its corresponding ordering schemas show their reflexes in the languages of the world. [...] We shall be dealing with oppositeness in the sense that a linguistically untrained native speaker, when asked what would be the opposite of 'long' can come up with some such answer as 'short', and likewise intuitively grasp the relation between 'man' and 'woman', 'corne' and 'go', 'up' and 'down', etc. Thinking that much of the vocabulary of a language is organized in such opposite pairs we must recognize that this is an important faculty, and we are curious to know how this is done, what are the underlying conceptual-cognitive structures and processes, and how they are encoded in the languages of the world. We shall leave out of consideration such oppositions as singular vs. plural. present vs. past, voiced vs. unvoiced, oppositions that the linguist states by means of a metalanguage which is itself derived from a concept of oppositeness as manifested by the examples which I gave earlier. Our approach will connect with earlier versions of the UNITYP framework. However, as a novel feature, and, hopefully, as an improvement, we shall apply some sort of a division of labor. We shall first try to reconstruct the conceptual-cognitive content of oppositeness and to keep it separate from the discussion of its reflexes in the individual languages. We shall find that a dimensional ordering of content in PARAMETERS and a continuum of TECHNIQUES is possible already on the conceptual-cognitive level. In order to keep it distinct from the level of linguistic encoding we shall use a separate terminology, graphically marked by capital 1etters.
