In a recent online presentation, editors and researchers working on a first-of-its-kind dictionary of African American English gave a status update on the project. As academics explained their various methodologies, slides displayed behind them showed words that are more often associated with Twitter than Oxford: “Bussin,” virtual attendees were told, means impressive or tasty, while a “boo” is a lover. Those were two of the first 100 words that the Oxford University Press said it had prepared to include in the Oxford Dictionary of African American English, the hopeful result of the three-year research project announced last spring.
