What is a specialized language used within a subculture known as?

The correct answer is 'Argot.' Argot refers specifically to a specialized language used by a particular group or subculture, often to create a sense of identity or exclusivity within that group. It is characterized by unique terms and expressions that may not be understood by outsiders, serving as a form of communication that reinforces group solidarity and differentiates members from non-members.

In contexts like the mortuary science field, professionals may use argot to discuss processes, tools, or practices that are not commonly known outside of the profession. This helps to facilitate clear communication among practitioners while also creating a boundary of understanding around the specialized knowledge they possess.

The other terms, while related to language and communication within specific contexts, do not capture this concept with the same precision. Dialect focuses more on regional variations of a language. Jargon typically applies to the technical language specific to a profession but can be understood by outsiders familiar with the field. Ethnolect pertains to the unique speech patterns associated with ethnic groups, which may not necessarily reflect the exclusivity seen in argot.
