The present chapter summarizes the patterns of lexical derivation in Slavic languages. Lexical derivation is presented here as word formation. Words are formed in the sentence by word-structure rules that expand root categories like N and A to derived structures like N[A–N] and A[N–A], followed by the lexicalization of the root and suffix categories with morphemes from the lexicon. Differing from the morpheme approach to morphology is the word approach, which assumes a lexicon of words and favors processes over items. The author presents basic patterns of prefixation, suffixation, and suffixless recategorization.

This chapter presents the patterns of composition in Slavic languages. In Slavic, most compounds are nouns (like čel-o-věkъ) and adjectives (like *bos-o-nògъ). Verbal compounds (like blag-o-sloviti ‘to bless’) are less frequent and less productive (as is generally the case in Indo-European languages). The author reviews patterns and phenomena of nominal, adjectival, adverbial, verbal, pronominal, and numeral composition.

Basic principles of generative phonology, as codified in SPE, and later developments within this framework, including metrical phonology, lexical phonology, autosegmental phonology, and underspecification theory. The role of cyclicity. The rise of Optimality Theory and the difficulties encountered in this framework in accounting for opaque relationships.
