 “In the beginning was the Word…“                                           Approaches/ perspectives
• Almost everything in language is related to                    •   The orthographic approach
  words    central for understanding of                          •   The phonetic approach
           language                                              •   The phonological approach
• Psychological reality of words for speakers                    •   The semantic approach
• Associations between concept of word and                       •   The grammatical approach

• Words are vital for communication!?                                       interaction with other elements and linguistic

  constituents                                                   • Words have a characteristic internal structure:
     – Our topic is “Lexical semantics”.                           they normally have no more than one root

Word-formation                                 Relations between words

•   Blending                                      • E.g.: I talked to my mother yesterday.
•   Backformation                                 • Lexical relations are central to the construction
•   Acronyms                                        of meaning
