The purpose of this 3-year longitudinal study was to examine the role of three morphological awareness (MA) aspects (inflectional, derivational, and lexical compounding) in the spelling of specific morphemes. Two hundred and fifteen Greek children were followed from kindergarten (K) to grade 2 (G2). In K and grade 1 (G1) they were tested on measures of morphological awareness, letter knowledge, phonological awareness, rapid automatized naming, and general cognitive ability. At the end of G1 and G2, they were also tested on spelling of (a) inflectional suffixes in words and pseudowords, (b) familiar stems in simple words, and (c) familiar simple stems in low frequency derived words and in pseudowords with existing derived morphemes. The results of hierarchical regression analyses showed that the derivational aspect of MA in K and the lexical compounding aspect of MA in G1 predicted uniquely the spelling of inflectional suffixes in both words and pseudowords in G1 and G2 respectively. In addition, the lexical compounding aspect of MA in K and G1 predicted the spelling of familiar stems in simple words and the spelling of familiar simple stems in low frequency derived words in G1 and G2 respectively. Inflectional aspect of MA did not predict later performance in any spelling measure. These findings speak to the importance of early MA skills in spelling of specific morphemes and provide supportive evidence to those who suggest that morphological knowledge is part of children’s repertoire of strategies employed in spelling, even at the first stages of learning to spell.
