Jargon refers to specialized language used by a particular group, profession, or industry. It often includes technical terms and phrases that may be difficult for outsiders to understand. For example, in the field of medicine, doctors might use terms like "hypertension" instead of simply saying "high blood pressure." This can create a barrier for patients who are not familiar with such language. While jargon can help professionals communicate more efficiently among themselves, it can also lead to confusion for those not in the know. In everyday conversations, using too much jargon can alienate people. It's important to balance technical language with clear explanations, especially when discussing topics like technology or law.
