Purpose: Some variability in children's early productions of grammatical morphemes reflects phonological factors. For example, production of 3rd person singular "-s" is increased in utterance-final versus utterance-medial position and in simple versus cluster codas (e.g., "sees" vs. "hits"). Understanding the factors that govern such variability…

Children's early productions are highly variable. Findings from children's early productions of grammatical morphemes indicate that some of the variability is systematically related to segmental and phonological factors. Here, we extend these findings by assessing 2-year-olds' production of non-morphemic codas using both listener decisions and…
