What term describes vocabulary that is distinctive to a particular group sharing a vocation?

Jargon is a term that specifically refers to specialized vocabulary that is used by a particular profession, trade, or group. It often includes terms and phrases that are unique to that field, making it easier for members of the group to communicate complex ideas but can be confusing to outsiders. For instance, in fields like medicine, law, or technology, jargon encompasses specific terminology that is widely understood among professionals but not necessarily by the general public. This enables efficient and precise communication within the group while also serving to establish a sense of identity and belonging among its members.

In contrast, dialect refers to variations in language based on geographic or social factors, colloquialisms are informal expressions that are often regionally specific, and slang consists of informal and often transient words or phrases popular among particular groups or in certain contexts. These terms do not carry the same level of specificity or professional connotation as jargon does, making jargon the most accurate answer for describing vocabulary distinctive to a particular vocation.
