Morphology is the study of word structure and its meaning. Knowledge and awareness of morphological structure provides a new light to help students with reading disabilities build skills in their word reading and spelling. When teaching morphology, teachers can focus on four literacy components (Claravall, 2013): morphemic analysis, vocabulary and spelling, contextual reading, and written expression. In this article, the author introduces five principles to guide teachers in designing morphology instruction. This instruction will help students to understand that morphologically complex words found in literature, social studies, science, and math have structures, and that these components can be broken down into different substructures (e.g., base word, prefix, suffix, inflection, Greek and Latin roots).
