Written morphological analogies in Hebrew Dorit Ravid and Rachel Schiff Tel Aviv University Bar Ilan University Israel Morphology • One of the organizing principles of the mental lexicon • Morphemes and words Morphology • One of the organizing principles of the mental lexicon • Morphemes and words • Crucial importance in Hebrew – Highly synthetic Semitic language Hebrew morphology: Roots and patterns katav hixtiv katuv mixtav kituv wrote dictated written letter subtitle któvet ktav ktiv katvan katava address writing spelling typist journalistic report hitkatvut ktuba correspondence marriage contract taxtiv dictate Roots and patterns: k-t-b ‘write' כתב katav hixtiv katuv mixtav kituv wrote dictated written letter subtitle כתב הכתיב כתוב מכתב כיתוב któvet ktav ktiv katvan katava address writing spelling כתובת כתב hitkatvut כתיב typist כתבה כתבן ktuba correspondence marriage contract התכתבות כתובה journalistic report taxtiv dictate תכתיב Roots (k-t-b, g-d-l, p-r-s-m) Spoken roots • • • • Discontinuous 3-4 consonants Phonological alternations Lexical core of morphological family • Salient Written roots • • • • Almost continuous 3-4 letters Consistent orthography Construal as entity fostered by written properties Patterns (hiCCiC, CaCuC, miCCaC) • • • • Spoken patterns Discontinuous Prosodic templates Provide internal vowels (+ prefixes / suffixes) Categorial meaning – Verbal – Nominal • Less salient than roots • • • • Written patterns Scant orthographic representation Vowels: almost no representation Discrete prefix, suffix Construal as entity obscured by written properties Implications for reading and writing • The lexically meaningful part of the word is represented in its center; letters framing the word carry grammatical and categorial meaning • WKŠBMGDLYKM וכשבמגדליכם u-xshe-be-migdaley-xem ‘and-when-in-towersyoursPl’ • Root GDL ‘grow’ surrounded by function elements The current study • Investigates Hebrew readers’ ability to analyze roots and patterns in written Hebrew wordforms • Focus on nominal patterns • Testing the ability to extract and recombine roots and patterns from written Hebrew nominals using a morphological analogies task Participants 1. 152 gradeschool children, middle-high SES 2. 167 gradeschoo children, low SES – – Five age-groups each: 2nd, 3rd, 4th, 5th and 6th graders All monolingual speakers of Hebrew as a native tongue with no diagnosed language or learning disabilities 3. 38 undergraduate education students, all with a long history of reading difficulties and diagnosed with reading disabilities within three years prior to attending university or while attending university; All monolingual speakers of Hebrew as a native tongue The Morphological Analogies Task (MAT) • 40 analogy sets • Each set contains two components: – A set of stimulus nouns – A set of possible responses • The task requires the selection of a target noun from the set of responses to complete the stimulus set Analogy structure P a t t e r n r e l a t i o n s h i p Root relationship KPL כפל kéfel ‘multiplication’ MKPLH מכפלה maxpela ‘multiple,N’ SRŦ סרט séret ‘film’ Pattern source ?
