What is a technical language?Scientists have been trying to define it since the beginning of the 18th century, so many interpretations have been made. They began discussing terms and vocabularies to define technical language. A couple of years later they emphasized the importance of text and nowadays they talk about text from the point of view of communication. Anglo-Saxon society considered language a system, so it found little interest in technical language. This is one of the reasons why technical language has often remained missing. But this was not the case with the Prague School. They found sociolinguistics and technical language very interesting. The Prague School used a horizontal dimension to describe the classification of technical linguistic areas. A vertical dimension was used to describe the different levels of use. The third dimension was based on expressions and communication, both oral and written. The communication dimension is often used to check whether a text should be classified as technical language or not. The result can be seen as a cube. A downside to studying this model is that it can be easily misunderstood. When a sender and a recipient are experts in the topic being discussed, they will likely use technical language. On the other hand, they may have different knowledge and may discuss new information. The main idea is that they have the opportunity to use the established technical language. However, it is almost impossible to separate rigorous technical language from colloquial language. A scale was created to classify the different levels of technical language in the geographical area. We are clearly dealing with technical language when the sender and the recipient have the same knowledge on a specific topic, for example communication between geographers. The next level is when the sender needs to introduce the topic to the receiver, for example when a geographer communicates with a student. And the final level is when the sender must explain everything to the recipient, for example, when a geographer communicates with an amateur. Text type, a kind of style model, is a term found in technical language. A textbook is an example. Technolects are found in heavy scientific material, for example in reports, while text types are found in less complicated compositions such as business letters.
