In various circumstances, the same word can mean differently based on the usage of the word in a particular sentence.The aim of word sense disambiguation (WSD) is to precisely understand the meaning of a word in particular usage.WSD utilized in several applications of natural language to interpret an ambiguous word contextually.This paper enhances a statistical algorithm proposed by Abdo [36] that performs a task of WSD for Afaan Oromoo (one of underresourced language spoken in East Africa by nearly 50% of Ethiopians).The paper evaluates appropriate methods that used to increase the performance of disambiguation for the language with and without morphology consideration.The algorithm evaluated by 249 sentences with four evaluation metrics: recall, precision, F1 and accuracy.The evaluation result has achieved state of the art for Afaan Oromoo.Finally, future direction is highlighted for further research of the task on the language.
