I have a theory about why certain news anchors have prounounced Lupita Nyong’o‘s last name as Enn-yongo. I think it began 53 years ago when President Kennedy welcomed Ghana’s chief of state Kwame Nkrumah, whose last name Kennedy pronounced (apparently correctly) as “Enn-krumah.” I think that vocal impression (a clipped New England accent pronouncing an exotic African name) lingered in the back of people’s minds and perhaps was passed along to today’s newscasters by their parents. I don’t have any hard research to back this up, but this is a perfectly reasonable and plausible theory.
