Why spell Afrika with a K?
According to the Afrikan-American poet and writer Haki Madhubuti in his From Plan to Planet (1973)
Europeans particularly the Portuguese and British, polutted Afrikan languages by substituting ‘C’ whenever they saw ‘K’ or heard the ‘K’ sound B as in Kongo and Congo, Akkra and Accra, Konakri and Conakry B by substituting Q whenever they saw KW. No European language outside of Dutch and German has the hard ‘C’ sound. Thus, we see the Dutch in Azania calling and spelling themselves Afrikaaners.
We are not certain of the origin of the name Afrika, but we are sure the name spelled with ‘C’ came into use when Afrikans were dispersed over the world. There the ‘K’ symbolizes our coming back together again.
