Given the growing evidence of the integral role that semantic development plays in normal child syntactic acquisition, it is very likely that lexical-semantic deficits can have ramifications for a child's grammar. This paper illustrates how semantics and syntax interact in a case study of a child, 5;3 years, with apparent grammatical deficits. Using concepts from Principles and Parameters Theory, a language sample analysis revealed that what appeared to be purely grammatical deficits arose via underlying lexical-semantic mechanisms. Language sample analyses to adequately guide intervention planning may thus need to move beyond superficial surface structures and utilize linguistic frameworks capable of addressing the interaction among language-internal components.
