Meaning of Semiotics
What is Semiotics:
As semiotics, the discipline in charge of the study of the sign is known, that is, that which is used to represent an idea or an object different from itself. The word, as such, comes from the Greek σημειωτική (semeiotiké).
The first notions of semiotics are found in the General linguistics course, by Ferdinand de Saussure, in which he had conceived the possibility of a science that would be in charge of studying signs in the bosom of social life.
As such, semiotics addresses the interpretation and production of meaning that is generated from the sign, although it does not deal with meaning, which is the field of semantics; nor of the denominations, including the verbal ones, that form part of the scope of the lexicology, the lexicography and the onomastics; nor is it responsible for the non-verbal ones, which are the object of attention of symbology, iconography and iconology.
In this sense, what semiotics studies and analyzes are all the phenomena, objects and systems of meaning that concur in languages and discourses to produce meaning. Thus, all production and interpretation supposes a significant practice, which occurs through signs and is specified in texts.
Likewise, as semiotic or semiotics, what belongs to or related to the discipline of semiotics can be designated: "He spoke from a semiotic approach."
Semiotics and semiology
Semiotics is the study of the sign in general, while semiology is the study of signs in social life. In this sense, semiology is related to linguistics, since it encompasses human sign systems (verbal, gestural, etc.) that are typical of life in society. Thus, semiology is the discipline in charge of studying what an image, a gesture, a behavior, an object or a set of words mean for a given society.
Semiotics in Medicine
As medical semiotics or medical semiology, the part of medicine that studies and classifies the signs of diseases is known to interpret, rank and reason them, with the aim of reaching a diagnosis and a prognosis.
