This document summarizes key concepts from a seminar on semantics and word properties. It discusses how dictionaries provide phonological, grammatical, and semantic information about words. Specifically, it examines how dictionaries represent the different senses of words like "man" and "human" as separate entries. The document also distinguishes between the goals of linguistic semanticists who study word meanings, and encyclopedias which provide factual information. Finally, it notes that the distinction between dictionary definitions and encyclopedic information is blurring, as understanding word meanings involves world knowledge.
