In a recent research note entitled “Grammatical Morpheme Acquisition in 4-Year-Olds With Normal, Impaired, and Late-Developing Language” (JSHR 36, 1271–1275), Paul and Alforde concluded that “grammatical morphemes present special difficulties for children with language disorders … even when MLU … is taken into account.” This position is certainly held by others, and I am not writing to argue against such a position. Rather, my concern is with the use of Brown’s (1973)  stages, as assigned to morphemes by Miller (1981), as the normative data from which conclusions were drawn about deficits in the morphological development of children with language impairments.
