Slides adapted from Dan Jurafsky Jim Martin and Chris Manning Three Perspectives on Meaning Lexical Semantics The meanings of individual words Formal Semantics or Compositional Semantics or Sentential Semantics. Chapter 8. The term . derivational relations . refers to the type of word knowledge that more advanced readers and writers possess. Spelling and vocabulary knowledge at this stage develop primarily through processes of derivation in which new words result from the addition of prefixes and suffixes to a single base word or word root. Exploration of words at the derivational relations stage prompts more extensive experience in reading and writing skills. There is a close correlation between growth in vocabulary, spelling knowledge, and the amount of reading and writing that occurs in the derivational relations spelling stage. Julia Hirschberg.
