Here are some possibilities and their potential connotations:
* "Common use dialect" as a general term for any dialect spoken by a large number of people: This is a bit broad, and the connotations would depend on the specific dialect. Some commonly spoken dialects might have connotations of informality, familiarity, or a lack of prestige compared to standard varieties. However, others might be seen as authentic, vibrant, or powerful. Ultimately, the connotation would depend on the specific dialect, its historical context, and how it is perceived by different individuals and groups.
* "Common use dialect" as a synonym for "vernacular" or "colloquial" speech: In this case, the connotations would likely be informal, familiar, and sometimes considered less formal or sophisticated than standard language. However, it's important to remember that vernacular speech can be just as rich and expressive as standard language, and it plays a vital role in shaping a language's evolution.
* "Common use dialect" as a specific dialect with a particular name: If you have a specific dialect in mind, please let me know! I can then provide you with more specific connotations associated with that particular dialect.
