Development of phonological, morphological, and orthographic knowledge in young spellers: The case of inflected verbs

This study was designed to simultaneously investigate the influence of phonological, morphological, and orthographic awareness skills on the ability to spell inflected verbs in structured spelling tasks. Children in grades 1, 2, and 3 (n=103) spelled inflected past and progressive tense verbs and completed awareness tasks. Developmental changes occurred in the ability to include the inflected ending, to spell the ending consistently reflecting the correct morphological unit, and to affix the ending using the correct orthographic pattern. The contributions of phonological, morphological, and orthographic awareness to spelling development varied across the three grades but were similar for each sub-component, suggesting a developmental relationship between the ability to spell inflected verbs and linguistic and orthographic awareness.
