- Pharos English for all

Etymology/South Africanisms:

A staple food for many in South Africa is mealies. The word has a convoluted etymology: it is a re-spelling of the Afrikaans mielie, which is probably derived from the Portuguese mihlo, which in turn comes from Latin milium for grain, especially millet. In his Long Walk to Freedom (1994), Nelson Mandela points out that 'Maize (what we call mealies and the people in the West call corn)', along with sorghum, beans and pumpkins, made up most of his childhood diet, 'not because of any inherent preference for these foods, but because the people could not afford anything richer'.
