The Pan-Nigerian alphabet is a set of 33 Latin letters standardized by the National Language Centre of Nigeria in the 1980s. It is intended to be sufficient to write all the languages of Nigeria without using digraphs.
Several hundred different languages are spoken in Nigeria. The different Latin-based alphabets impeded the use of typewriters. In the 1980s the National Language Centre (NLC) undertook to develop a single alphabet suitable for writing all the languages of the country, taking as its starting point a model proposed by linguist Kay Williamson in 1981. The final version and reference typeface were developed by the typographer Hermann Zapf in 1985.
