definition of semiology

Semiology is one of the sciences that are part of the study of communication since it is responsible for analyzing the different types of symbols and signs produced by humans to communicate as well as their meanings and signifiers. Semiology is understood in many cases as the equivalent of semiotics.

When communicating, the human being uses countless types of symbols and signs that are the means through which some type of message is projected. Both when speaking or writing and when establishing images as symbols, the human being sends a message to a certain receiver and can thus communicate. Even the words are composed of symbols that are the letters and that allow the idea that remains in the head of a person to be transmitted abroad in a written or spoken way.

Symbols can have a specific and accepted meaning (as, for example, the signs used for driver education have) as well as they can have a particular meaning that each individual gives them according to their experiences, situations, sensations and knowledge. The task of semiology is precisely to analyze this type of communication. The meanings can also vary from culture to culture, from society to society and this is where sciences such as anthropology or archeology also come into play.

Symbols always have some meaning that may be more or less obvious depending on the case. Spaces or situations such as rituals, ceremonies, events or even the most everyday and normal ones serve as spaces for semiology to act and analyze the meanings behind each communicative act, behind each message transmission, etc. Symbols are used in many spaces such as religion, art, medicine, the military world, economics, mathematics, etc.
