The document discusses componential analysis, a method proposed by structural semanticists to analyze word meanings. It breaks down words into semantic features or components, using plus and minus signs. Examples are given of decomposing the meanings of words like "man", "woman", "boy", "girl" into their semantic components. Componential analysis provides insight into word meanings and how words related in meaning are related. It allows analyzing synonyms, cultural words, and translating neologisms or new words not found in dictionaries. The method focuses on universal components of word meanings beyond linguistic and cultural differences between languages.
