Foundations of Morphology | Ch 04: Derivational Morphology | Video

Corrections: 05:20 Base restrictions are strong tendencies with exceptions and creative contexts. Satisfying a restriction does not guarantee an established word (textbook pp.59–61). Chapter 4: Derivational Morphology Foundations of Morphology: For EFL University Students Video lesson • Printed textbook pages 54–67 This chapter explains how derivation creates new lexemes. It examines the categories and meanings of affixes, restrictions on their bases and order, and differences between native and borrowed patterns across languages. Central question: How do derivational processes create new words, and what limits which affixes can combine with which bases? Learning objectives 1. Distinguish derivation from inflection by asking whether a process creates a new lexeme or a word-form of one lexeme. 2. Identify the input and output categories of derivational affixes and classify affixes as category-changing or category-preserving. 3. Describe common meanings of derivational affixes, such as agent, instrument, negation, reversal and size, and recognize affix polysemy. 4. Explain why some combinations of affix and base are impossible, using base restrictions and affix order. Five core topics 4.1 Two Kinds of Morphology: Creating Words and Creating Word-Forms (p. 55) Distinguish derivation, which creates new lexemes, from inflection, which creates grammatical forms of an existing lexeme. 4.2 Derivational Affixes and Word Classes (p. 56) Identify the input and output word classes of affixes and distinguish category-changing from category-preserving derivation. 4.3 Meanings of Derivational Affixes (p. 58) Interpret recurring affix meanings, including agent, instrument, negation, reversal, repetition, and size, while recognizing polysemy. 4.4 Restrictions on Bases and Affix Order (p. 59) Explain how sound, word class, meaning, and origin restrict bases, and use those restrictions to analyze affix order. 4.5 Native and Borrowed Affixes and Derivation across Languages (p. 62) Compare native and borrowed affixes, their preferences and exceptions, and derivational patterns in languages beyond English.
