Pickaninny (also picaninny, piccaninny or pickininnie) is a pidgin word for a small child, possibly derived from the Portuguese pequenino ('boy, child, very small, tiny').[1] It has been used as a racial slur for African American children and a pejorative term for Aboriginal children of the Americas, Australia, and New Zealand. It can also refer to a derogatory caricature of a dark-skinned child of African descent.[2]
