Term
Derivational morphology
Definition
The process that creates new words by adding certain suffixes or prefixes to existing words (Such as dance+er=dancer)
Term
Inflectional Morphemes
Definition
Morphemes that make a word fit into the grammar of the sentence
Term
Derivational Morphemes
Definition
Creates a new word with a new meaning
Term
Regularization errors in Inflectional Morphemes
Definition
mouses, eated, goed, bringed, brang, branged
Term
Allomorphs (allomorphemes)
Definition
Version of a morpheme that depends on phonological environment
Term
Berko Wug Test
Definition
Designed as a way to investigate the acquisition of the plural and other inflectional morphemes in English-speaking children.
Term
Berko Wug Test
Definition
The child is presented with some sort of pretend creature, and told, "This is a wug." Another wug is revealed, and the researcher says, "Now there are two of them. There are two...?" Children who have successfully acquired the allomorph /z/ of the plural morpheme will respond: wugs /wʌɡz/
Term
Overregularization
Definition
foot-->*foots, eated, mouses are an Ex. of what?
Term
Rule-based Overregularization
Definition
use rules they know to overregularize
Term
Kiparsky’s Level Order Model of Morphology
Definition
Basic features of __________:
There are different types of morphological rules (or morphemes):
Rules of a given type must apply before rules of a second type (i.e., they are ordered)
These “blocks” or types of rules define LEVELS in the model.
Term
Level 1 Rules of Kiparsky’s Level Order Model of Morphology
Definition
• Derivational morphemes that are unproductive and semantically unpredictable (e.g., -ion, -ous, -ity, -th, in-)
• Inflectional morphemes that are irregular (e.g., foot -> feet, eat -> ate)
• Properties: Adding a Level 1 morpheme often has phonological effects on the base or root morpheme (e.g., -ion
o Shift in stress pattern: photograph - > photography, Economy >ecoNOMic)
o Vowel reduction: economy -> economics
o Vowel change: eat -> ate, goose - > geese
o Consonant changes: populate - >population
Term
Acquisitional Predictions of Kiparsky’s Model
Definition
All level 1 rules apply before level 2 rules which apply before level 3 rules: Predictions
Term
Level 2 Rules Kiparsky’s Level Order Model of Morphology
Definition
Derivational morphemes that are
• Fairly productive
• Fairly semantically predictable
• Non-stem deforming
• Examples :
o Compounding: base+ball
o Agentive –er: teach+er
Term
Level 1 occurring before level 2 according to Kiparsky’s Level Order Model of Morphology
Definition
reactions not reactsion is an example of what?
Term
Level 1
Definition
economy -> economics is an example of what level?
Term
Level 2
Definition
teach+er is an example of what level?
Term
Level 3
Definition
s plurals, -ed past tense, progressive –ing, possessive –s are examples of what?
Term
Bound Morphemes
Definition
o A morpheme that cannot stand alone, but rather is attached to a word stem
Prefixes, suffixes, and, in some languages, infixes
Term
Bound morphemes
Definition
-ment in "shipment", or pre- in "prefix", while some are unbound, e.g., in- in "incoming" are examples of what?
Term
Affixes
Definition
is a morpheme that is attached to a word stem to form a new word. _______ may be derivational, like English -ness and pre-, or inflectional, like English plural -s and past tense -ed.
Term
Derivational morphemes
Definition
can be added to a word to create (derive) another word: the addition of "-ness" to "happy," for example, to give "happiness." They carry semantic information.
Term
Inflectional morphemes
Definition
modify a word's tense, number, aspect, and so on, without deriving a new word or a word in a new grammatical category (as in the "dog" morpheme if written with the plural marker morpheme "-s" becomes "dogs"). They carry grammatical information.
Term
Inflectional Morphemes
Definition
Closed class & few in number.
