Stage 1 of Morphological Development
one word stage
-words = single roots
-no affixes
-regular/irregular forms are learned on a case by case basis ex. get/got, child/children
Stage 2 of Morphological Development
overgeneralization
-overuse of general rules
-kids learn one rule and assume its used everywhere
ex. get/getted, child/childs, thought/thinked
Stage 3 of Morphological Development
exceptions to general rules learned later
-“errors” are mistakes from the adult perspective, but reflect the childs current grammar
