patois
This term often carries a sociological weight, frequently implying a hierarchy where the spoken variety is viewed as a corruption or a simplified version of a prestige language. It evokes a sense of local identity and cultural heritage, yet it can be used pejoratively to describe speech that is perceived as uneducated or rustic.
When applied to professional fields, the word shifts toward the concept of jargon. In this sense, it describes a linguistic barrier intentionally or unintentionally created by experts, transforming the language into a tool for exclusivity rather than just a regional marker.
