Issue is Black Americans are a mix of numerous African ethnicities:
Wolof
Mandinka
Mende
Fulani
Twi
Akan
Igbo
Edo
Yoruba
Kongo/Kikongo....and on and on
Then, the average Black person in America is between 10% and 30% Euro (mostly rape, sometimes consensual before Bacon's Rebellion; indentured white females + Black male slave...rare)....so throw in:
English (Saxon)
Scottish (Scottish Gaelic)
Welsh (Celtic/Briton)
Irish (Irish Gaelic)
French
Spanish (especially in LA/TX)
German & Dutch in rare cases
Norwegian and Danish - only because most brehs have English/Irish Scottish ancestry and the Vikings were all up in there. Go back 1100 years and most brehs got at least a few Ragnar's and Lagertha's on that family tree
Mandarin - you had Asians in Madagascar and most Black Americans have the "Malagasy trace" due to small numbers of people from there being enslaved and brought to Virginia. Most Black Americans on 23andMe got a tiny bit of Asian because of these people from back in the 1600s.
All the Native American languages from Creek to Seminole, Choctaw etc.
Hindi for the Caribbean brehs with East Indian fam...a decent number of y'all got that, even if it's a small amount.
In other words - Black Americans, Caribbean brehs etc., don't have a single language our ancestors spoke because our ancestors spoke a SHYT LOAD of languages. Even a breh that's American or Caribbean but 100% West/Central African is a mix of different languages.
All the languages are our languages damn near.
