Long before Namibia's independence from South Africa, SWAPO was of the opinion that the country should become officially monolingual, choosing this approach in contrast to that of its neighbour South Africa (which granted all 11 of its major languages official status), which was seen by them as "a deliberate policy of ethnolinguistic fragmentation." Consequently, SWAPO instituted English as the sole official language of Namibia though only about 3% of the population speaks it as a home language. Its implementation is focused on the civil service, education and the broadcasting system. Some other languages have received semi-official recognition by being allowed as medium of instruction in primary schools.
