Semiology is one of the sciences that are part of the study of communication, as it is responsible for analyzing the different types of symbols and signs produced by human beings to communicate, as well as their meanings and signifiers. Semiology can be understood in many cases as the equivalent of semiotics.
When communicating, the human being uses a multitude of symbols and signs that are the means to project some type of message
Both when speaking and writing, as well as when establishing images as symbols, the human being sends a message to a specific receiver in order to communicate. Words are even made up of symbols, in this case letters, allowing the idea of keeping them in the person’s memory and thus being transmitted to the outside of writing or speech.
Symbols can have a specific and accepted meaning (for example, the signs used in vial education ) as well as they can have a particular meaning where each individual is in agreement with their experiences, situations, feelings and knowledge. The task of semiotics is precisely to analyze this type of communication. Meanings can also vary from culture to culture , society to society ; this is where certain sciences like anthropology or archeology come into play.
Symbols always have a meaning that can be more or less evident, depending on the case.
Spaces or situations such as rituals, ceremonies, events or even the most everyday and normal ones serve as spaces for the action of semiotics and the analysis of the meanings of each communicative act, each transmission of messages, etc. Symbols are used in many areas, such as religion, art, medicine, the military world, economics, mathematics, among others.
