The intellective analysis of language and linguistic facts consists in analysing the mental process of the creation of meanings to discover the intellective operations producing speech in the human conscience of speakers. Language is nothing but the sheer relationship of creation collaboration and participation between an I who creates concepts and ideas mentally representing them in objective symbols and a You who interprets, both relieving each other in their respective roles, in dialogos (- =by means of logos=both thinking and saying) when words reverberate. The nature of adjectives must be defined in terms of the different types of meaning they convey, the parameters having prompted the formation of them, and the modes of thinking implicit. This book is based on the conclusions drawn in my book, Significado y conocimiento. La significación de los adjetivos subjetivos, Granada Lingvistica 2002.
