Аннотация:Reading involves the decoding of written forms into language forms that represent phonological, morphological, and word level units. Thus, orthographies convey not only phonological but also morphological information-the word roots, syntactic inflections, and derivational relations that constitute the minimal semantic and grammatical units of a language. There are many psycholinguistic issues brought to light by the facts about morphology. However, the central one has focused on decomposition-whether and how language users, including readers, decompose morphologically complex words into their constituent morphemes.
