概要	Prototype Theory is a framework for understanding how humans categorize concepts, proposing that categories are organized around prototypes—the most typical or central members. Developed by Eleanor Rosch in 1973, the theory challenges classical logic's view that categories have fixed boundaries defined by necessary-and-sufficient features. Instead, prototypes have fuzzy boundaries and graded membership: some instances are more central (robin is a prototypical bird) while others are peripheral (penguin is a bird but less typical). Prototype Theory has profound implications for understanding language, cognition, and meaning.	Semantic Feature Analysis, or Componential Analysis, is a method for understanding word meaning by decomposing concepts into minimal meaningful units called semantic features or components. Developed by Ward Goodenough in 1956, this approach represents the meaning of words as bundles of features (e.g., 'woman' = [human] [adult] [female]), enabling systematic analysis of semantic relationships, kinship systems, plant classifications, and lexical fields. The method is grounded in structural linguistics and has applications in anthropology, cognitive linguistics, and lexicography.
