Setswana Dictionary The dictionary documents both colloquial (informal) and formal Setswana and uses style marks to separate colloquialisms, thus, coinciding with Trench’s claim, stating that, ‘a dictionary must contain all the words of a language without prejudice’. Also, it represents the lexical variety of Setswana in a manner that hasn’t been attempted previously. Dialectal variations such as Sengwaketse, Sekgatla and others as well as terms found exclusively in the South African Setswana speaking community are equally documented with dialectal marks. Tlhalosi ya Medi ya Setswana has over 1, 500 idiomatic expressions and for the first time it has full phonemic transcriptions with tonal markings. There is also a frequency band which shows which words are rare or frequent in the language. The dictionary is impressive in many ways, for example, it has full etymological information- borrowed words are traced to their roots, either to Zulu, English, or Afrikaans, it also has lexical synonymy which links synonyms together or links idiomatic to other dictionary headwords. Another impressive feature is its central part; lexicographically called ‘the dictionary middle matter’ which in some detail discusses issues such as punctuation, time in Setswana, the importance of rain and the cow to a Motswana.
