African-American culture is also known as black culture. In the United States, it refers to the cultural contributions of African Americans to the culture of the United States. It could be either a part of, or distinct from American culture. Presently, the United States of America is so diverse ethnically and racially due to large-scale immigration of many different cultures throughout its history, dating back to the days of slavery. This paper will discuss how African communities have contributed to the social and cultural trait of the United States. The origin of titles referring to family members and bonds could be linked to relations of the ancient Africans. It was common for family members to be separated through the sale of persons in the days of rampant slavery in the United States. However, some African people who had gained freedom by being hired out or escaping from their masters, managed to buy back members of their families who were still in bondage. Some who were separated from blood relatives formed close relations based on assumed kinship. The close bonding of non-blood family friends led to their being accorded the status and titles of blood relatives (Opala, 2008). Therefore, the African concept of what constitutes family, and the high regard for elders, who form part of African traditional societies may be the origin of common use of household terms such as brother, sister, uncle, aunt and mama (Ferris, 2009).
