Semantics is the study of the significao of the vocbulos and the transformations of felt why these same vocbulos pass. During its history nor always vocbulo keeps its etimolgico direction, that is, originary. For reasons we variadssimos the direction exceeds the limits of its primitive ‘ ‘ sphere semntica’ ‘ assumes new values. ‘ ‘ The vocbulos move of sensible or because the things if modify or because ‘ ‘ constellation psquica’ ‘ under whose influence the direction of the object is born, if it modifies thanks to causes diversas’ ‘.
The significao of the vocbulos closely is related with the world of the ideas and the feelings; ‘ ‘ between: ideas, enter the thoughts do not have absolute separation, therefore that the associations if establish, without ceasing, of ones for outros’ ‘. In another article of my authorship, I looked for to understand the variations of the semantic lexicon in the words that Cames used to compose the workmanship ‘ ‘ The Lusadas’ ‘. I want here it withhold me it semantics; what I observed in the employed study was that the formal semantics, the semantics of the articulation or argumentativa and the cognitiva semantics, for example, studies phenomenon the same, but with different concepts and approaches, and that the all moment the all moment appears words. Some enter in disuse, others come back to be used with a new concept, (…). We can observe that in the Portuguese language, the meaning of the words leads in consideration: Synonymy: It is the relation that if establishes between two words or more than they present equal or similar meanings, that is, the synonymous ones: Antonmia: It is the relation that if establishes between two words or ais that present different meanings, contrary, that is, the antonyms: Homonmia: It is the relation between two or more words that, although to possess different meanings, possess the same fonolgica structure, that is, the homonyms.
