Componential analysis (feature analysis or contrast analysis) is the analysis of words through structured sets of semantic features, which are given as “present”, “absent” or “indifferent with reference to feature”. The method thus departs from the principle of compositionality. Componential analysis is a method typical of structural semantics which analyzes the structure of a word's meaning. Thus, it reveals the culturally important features by which speakers of the language distinguish different words in the domain (Ottenheimer, 2006, p. 20). This is a highly valuable approach to learning another language and understanding a specific semantic domain of an Ethnography.
