Complexity and sequence constraints in a Granada Spanish-speaking four-year-old with protracted phonological...

This article describes the phonology of a Granada Spanish-speaking 4-year-old boy with Protracted Phonological Development (PPD) from the perspective of constraint-based nonlinear phonology. Although he had acquired basic word structure and a near-complete repertoire of vowels and consonants, he had difficulties producing more complex word structures (multisyllabic words, clusters, diphthongs) and producing sequences of consonant manner and place features across vowels. The analysis outlines his strengths and needs in phonological development, and proposes an intervention plan to address constraints on complexity and sequences.
