parlance

This term describes the specialized vocabulary and stylistic conventions of a particular collective, such as legal, medical, or technical circles. It carries a connotation of exclusivity or professional identity, suggesting a linguistic code that may be opaque to outsiders. Grammatically, parlance is an uncountable noun. It refers to a general manner of speaking rather than a discrete object, meaning it cannot be pluralized or counted with numbers; one does not refer to multiple parlances in a standard context.
