@conference{Stamouli 2001, author = "Stamouli, Spyridoula", abstract = "In this paper spontaneous speech data from a Greek SLI child (age 4.3) are presented with respect to the morphosyntactic properties of the verbal domain. The morphosyntactic categories under study are Tense, Aspect and Subject-Verb Agreement. The central observation about the child's verbal grammar is that tense marking appears to be the most problematic domain, whereas errors of S-V agreement are rare. Tense marking in obligatory contexts appears to be correctly used for present tense (90% correct use) but problematic for past tenses (56.8% correct use). Imperfective aspect predominates in verb forms, since Present tense is the most frequently used verb form. Verb forms marked for imperfective aspect underspecified for tense features (Past tense forms) substitute Perfective Past and Perfective modal forms in contexts that require verb forms marked for perfective aspect. S-V agreement is correctly marked in all persons singular and plural (over 98% correct marking).", address = "Θεσσαλονίκη", booktitle = "Studies in Greek Linguistics: Proceedings of the 21st Annual Meeting of the Department of Linguistics, School of Philology, Faculty of Philosophy, Aristotle University of Thessaloniki", keywords = "Specific language impairment; tense; aspect; agreement; verbal system", month = "12-14 Μαΐου 2000", organization = "Aristotle University of Thessaloniki, Faculty of Philosophy, School of Philology, Department of Linguistics", pages = "712-723", publisher = "Kiriakides Publications", title = "{T}ense, {A}spect and {S}-V {A}greement: {A} case study of a {G}reek-speaking child with {S}pecific {L}anguage {I}mpairment [in {G}reek] ", year = "2001", }
