The document discusses different types of lexical and semantic relations between words, including:
- Paradigmatic relations, which involve words that could replace each other in the same syntactic position based on semantic categories like countable/uncountable nouns.
- Syntagmatic relations, which occur between words that co-occur in the same sentence based on syntactic and semantic dependencies, like a verb requiring certain types of objects.
- The Natural Semantic Metalanguage (NSM) approach analyzes word meanings using a small set of semantic primes and reductive paraphrase into simpler concepts.
