This paper represents a partial condensation of the results of a study covering 14 months in a Russian-speaking child's phonological development. The original investigation tested a theory of phonological acquisition formulated by Olmsted (1971), finding that – though modifications were necessary to accommodate certain aspects of the Russian data – Olmsted's hypotheses were, by and large, upheld. The present paper gives the evidence in support of the theory and offers in addition some detailed information on the Russian-speaking child's acquisition of specific phones over the months examined.
