West Midlands English is a group of dialects of the English language. The traditional Black Country dialect is very old, and can be very confusing for outsiders. The language is said to be a throw back to Middle English and still contains words such as Thee, Thy and Thou. "'Ow B'ist", meaning "How beist thou?" is a common greeting, with the typical answering being "'Bay too bah", meaning "I bayn't be too bad". "I haven't seen her" becomes "I ay sid 'er". Somebody from the Black Country will often substitute the word "ar" instead of "yes".

Inhabitants are proud to be known as Black Country "folk" and resist hints at any relationship to people living in Birmingham, calling Birmingham "Brum-a-jum" (Birmingham's colloquial name is Brummagem). Residents of Birmingham (Brummies) meanwhile often refer to their Black Country neighbours as "Yam Yams", a reference to the use of "Yow am" instead of "You are".

The thick Black Country dialect is less commonly heard today than in the past. Midlands English is much more naturalistic, especially the Black Country variety which has frozen in time. Some New World dialects borrow some of the Old World characteristics of this dialect.
