This thesis, which is part of the project of Dawuro language documentation, investigatesrnthe changes that lexical items of the earlier Dawuro kingdom have undergone.rnThe study collects, describes and classifies the lexical items into different semanticrncategories such as honorific, political and traditional. The lexical items are furtherrncategorized into different sub-categories. Analysis is given to the lexical items from thernperspective of their origins, forms, occurrences as well as functions. Factors that havernbeen responsible for the changes in the lexical items are also discussed. As the studyrnreveals, its different linguistic and non-linguistic factors are responsible for the changesrnin the lexical items.rnPhonological and morphological changes that are responsible for changes in the lexicalrnitems have been examined in this study. The non-linguistic factors include the variousrnsocio-political and economic changes in the society. It is noted that following the end ofrnthe political system of the earlier Dawuro kingdom, several lexical items becamernoutdated. Following attitudinal shifts of the society also many others became out of use.rnVarious others also became replaced by other representations. In addition, there arernothers, which shifted their meanings as well as declined their uses. Many lexical itemsrnhave undergone in their semantic reference. As the study identified, they havernundergone extension of meaning or narrowing of meaning or even complete semanticrnshift. Based on the findings; thus, suggestions are given regarding appropriate measuresrnwhich should be taken to preserve the lexical heritages in Dawuro
