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 (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

Secondary root distracter: a word containing the same root
shared by members of the top horizontal pair KPYL ‫‘ כפיל‬double’
Semantic distracter: associated semantically or pragmatically but
not morphologically to left-hand member of horizontal pair

Summary and conclusions
• Analytical morphological skills from early on in
normally developing Hebrew speakers
– More in high-SES gradeschoolers, less in low-SES
• Dyslexics are ‘stuck’ with the analytic skills of
3rd and 4th graders
– Revert to non-morphological strategies absent in
typically-developing children
Summary and conclusions
• Roots perceived as the prime lexical construct in
Hebrew words
• Patterns less salient and their perception lags
behind that of roots
• But - impossible to solve the MAT without
recourse to both root and pattern
