Principles of phonological markedness have been used to explain the cross-linguistic distribution of sound classes and their acquisition. This paper argues that the same principles can also be used to understand spoken production deficits in acquired speech disorders (aphasia). The author presents the errors of an aphasic speaker and argues that the errors are driven by the elevation of constraints against complex phonological structure. He also uses the errors to support specific claims about the representation of certain sound sequences in American English, particularly the appearance of the palatal glide in post-consonantal position. Language internal data highlight an additional pattern in English phonotactics -- the tendency for the high round back vowel to be preceded by a palatal. An analysis of the grammar of American English and the grammar of the aphasic speaker is presented, followed by a discussion of the implications of this work on the study of aphasia and grammar more generally.
