Children's early spelling attempts (invented spellings) and underlying component skills were evaluated in a sample (N = 115) of 5-year-old children. Letter-sound knowledge and phoneme awareness were shown to be important predictors of invented spelling performance in this age group. The results also showed associations between invented spelling and measures of orthographic awareness and morphological processing. The findings support the view that invented spelling is a developmentally complex and important early literacy skill that involves phonemic awareness, letter sound knowledge, and other oral language skills and orthographic knowledge.
