African Languages WordNet is an ongoing project which is based on the English WordNet.WordNet is an electronic lexical database that groups words in synonym sets (synsets).In this project, words are translated from English to African Languages.As such, this paper comments on the semantic aspects of verbs in one of the African Languages, namely Northern Sotho, that are translated from English.Verbs are generally understood as expressions of action or state of being.These two languages are typologically dissimilar, with different cultural-historical backgrounds.Northern Sotho is a Bantu 1 language, agglutinating with extensive and productive use of affixes while English is not.In the first place, structural differences between these two languages pose equivalence challenges, both linguistically and computationally.Secondly, verb equivalents may not be affected by the same collocational restrictions in the source and target languages.Another issue is that a verb in one language may invoke certain connotations, which may not apply to its equivalent in another language.Finally, some concepts may be foreign and others culture-specific to one language and not the other, thus resulting in omission of some target language concepts.Attention to these equivalence challenges may enhance technological development of the target language lexicon.
