Languages are the main means of communication worldwide. Although there are a lot of obstacles, languages are clearly the most useful in achieving communication between individuals of this planet.
The differences in development at economic, social, political or cultural level can be explained or overcome when the dialogue between individuals takes place by communicating in a language. This is where the translator or the interpreter comes in to facilitate communication. We need communication in various situations where we find ourselves, and our messages need to be conveyed in a common language for the two participants in the dialogue.
In order for the process of communication to be successful, it is necessary for the two participants in the dialogue to be interested in the same subject, to know and understand the language. The translator intervenes when the latter two conditions are not fulfilled. We can say that in the history of humanity the role of the translator has been an essential one for the evolution of man. When tribe leaders met, they needed an interpreter in order to make decisions. Nowadays, when state leaders meet, the translator and the interpreter continue to prove essential for important decisions on a political, economic or cultural level. The papers or documents signed during these meetings or summits require translators. That is why a single communication error can change the course of such an important meeting. The consequences of such an error can be serious. For this reason, regarding these communication situations, the translator needs the help of a team.
So as long as humans interact by communicating, there will be a need for translators or interpreters.
