Hanna K. Ulatowska, Maria. Tł Sadowska, Danuta Kądzielawa · 2001
Grammatical disturbances characteristic of the Polish language are illustrated in a longitudinal study of a patient with aphasia. Disturbances of the inflectional system of nouns and verbs consisted of substitution errors on inflectional suffixes and verb prefixes. Errors also occurred in stem alternations in both nouns and verbs. Forms which were more complex and Jess frequent were more disturbed. There was also extensive use of highfrequency diminutive forms. Errors decreased over time with no change in the basic patterns of disturbance. Preservations of specific structures in the language were also noted.
