What is meant by jargon?

The term "jargon" refers specifically to the specialized language used by a particular profession or group. This language often includes terminology, phrases, and expressions that are familiar to members of that group but may be difficult for outsiders to understand. Jargon serves an important function by enabling efficient and precise communication among professionals, allowing them to convey complex ideas succinctly. For instance, in fields like medicine, law, or technology, jargon helps practitioners discuss intricate concepts without misunderstanding.

Other options do not accurately represent the definition of jargon. A form of poetic expression pertains to literary techniques rather than specialized communication within a profession. A narrative perspective refers to the viewpoint from which a story is told, and a plot device is a narrative element that drives the storyline forward. Thus, the correct understanding of jargon aligns perfectly with its role as a specialized language among a specific group or profession.
