The document discusses semantic features and their role in defining word meaning. Some key points:
- Semantic features are the smallest units of meaning that make up a word's definition. Words can be defined by a set of semantic features.
- Different words may share the same semantic features. Semantic features can also apply across different parts of speech.
- Knowing the semantic features of words allows us to understand how words are related through meaning (synonyms, antonyms) and to combine words semantically in sentences.
- Exercises are provided to identify semantic features of example words and distinguish words in different languages based on their semantic properties.
