Seminar paper from the year 2008 in the subject English Language and Literature Studies - Linguistics, grade: 2,3, University of Hamburg (IAA), course: Seminar Linguistik: Semantics: Understanding the meaning of words and their combinations, 18 entries in the bibliography, language: English, abstract: This term paper deals with the development of categorisation, concepts and prototypes in terms of cognitive psychology.
