What are technical words or terms that cause communication barriers called?

The term that refers to technical words or terms causing communication barriers is known as jargon. Jargon consists of specialized language or terminology used by a particular profession or group that may be difficult for outsiders to understand. This can create obstacles to effective communication, as those who are not familiar with the specific jargon may find it challenging to grasp the intended meaning, leading to misunderstandings or confusion.

In contrast, coded language typically refers to a style of communication that requires interpretation or insider knowledge, but it’s not exclusively about technical terms. Signs can refer to physical indicators or symbols that convey information, but they do not address the specific idea of language barriers caused by specialized terminology. The option labeled as Misc does not directly pertain to the concept of communication barriers, making jargon the most accurate choice in this context.
