Outline

1. Productivity
2. Predictability
3. Allomorphy
4. Organization of mental dictionary

1. Productivity

If mental dictionary contains just morphemes and rules for combining, then all rules should be entirely productive.

Entirely productive: English progressive

V + ing

 

running

walking

thinking

abrogating

mulching

dissing

being

having

going

etc.

Productive, but with some irregular forms: English past tense

V + ed, except for irregulars

wanted	kept
helped	went
damaged	sang
measured	rang
governed	hit
manufactured	sat

2. Predictability

Not productive, but predictable meaning, and widely available

A + ize 'make (something) A'

 

commercialize

modernize

standardize

relativize

prioritize

criminalize

But...

*pleasantize

*sickize

*worthyize

*terribilize

Partially productive, and only partially predictable

V + N "N that Vs"

 

tug-boat boat that tugs

cry-baby baby that cries

strong-box box that is strong

watch-dog dog that watches

light-house house that lights

hit-man man that hits

kill-joy *joy that kills

break-water *water that breaks

task-force *force that tasks

spend-thrift *thrift that spends

*teach-book book that teaches

*suck-course course that sucks

Diseases, especially inflammatory ones

 

-itis

 

appendicitis

arthritis

sclerotitis

bronchitis

hepatitis

tonsillitis

bursitis

meningitis

dermatitis

 

Based on these forms and the novel forms below, we can conclude that the suffix '-itis' in English appears to be productive, although only in the narrow domain of disease-names.

 

Monday-morningitis

test-itis

olive-itis

Descriptions of People

-ist

 

anarchist

chartist

communist

leftist

Marxist

feminist

Calvinist

sado-masochist

 

pianist

violinist

saxophonist

guitarist

linguist

 

racist

sexist

 

age-ist

size-ist

separatist

unificationist

 

*drummist

*Lutherist

The suffix '-ist' seems to be productive in English, based on the fact that we can easily coin novel words using the '-ist' suffix. However, the suffix '-ist' has multiple meanings in English, corresponding to (i) "advocate of", (ii) "user of/expert in", and (iii) "detractor of". Although use (iii) is probably only a recently developed use of this morpheme, it appears to be the most productive.

Competition between different morphemes

Creating nouns from adjectives

	-ity	-th	-ness
sincere	sincerity	sincerth	?sincereness
chaste	chastity	*chasteth	?chasteness
scarce	scarcity	*scarceth	scarceness
curious	curiosity	*curiousth	curiousness
warm	*warmity	warmth	warmness
deep	*deepity	depth	deepness
wide	*widity	width	wideness
red	*reddity	*redth	redness
sick	*sickity	*sickth	sickness
pleasant	*pleasantity	*pleasanth	pleasantness
happy	*happity	happith	happiness

Generalization:

(1) -ity and -th are in competition with one another - complementary distribution

(2) -ness is generally available, and does not compete with -ity or -th

Systematic gaps

 

sicker, faster, taller, happier, worthier, bigger, shorter, hotter, thinner,greener, redder, bluer

 

*thoughtfuler, *impracticaler, *reasonabler, *turquoiser, *emeralder

 

*funner

Environments

/-s/ after /p/, /t/, /k/, /th/, /f/

/-z/ after /b/, /d/, /g/, /v/, /a/, /u/, /r/, /l/ ...

4. How is mental dictionary organized?

Comparison with printed dictionaries. Where would we expect to find a word like 'sign' in different kinds of dictionaries.

Standard dictionaries: alphabetical order, following spelling (not sounds)

sieve, sift, sigh, sign

 

"sign" wouldn't be anywhere near other words that have the same sounds at the beginning, e.g. "psychology", "cycle"

Rhyming dictionaries: organized according to sounds at end of words

sign, line, decline, resign, confine

Thesaurus: organized according to meaning

sign: symbol, emblem, badge, mark, flag

Tip-of-the-tongue states

"a navigational instrument used in measuring angular distances, especially the altitude of sun, moon and stars at sea" (Brown & McNeill 1966)

 

subjects were asked to ...

 

guess the initial letter?

what other words come to mind?

what words rhyme with it?

 

if they were unable to retrieve the word directly, some things they might nevertheless know are:

 

starts with /s/

sounds like "secant", "sextet"

meaning related to "compass"

doesn't sound like "sexy"

 

[By the way, the word they were looking for is sextant]

Anomia

"inability to retrieve words from mental dictionary"

Category-specific anomias

a. animate vs. inanimate

inanimate: ok (wheelbarrow, submarine, umbrella, briefcase, compass)

animate: impaired (wasp, duck, holly, ostrich, snail)

b. fruits and vegetables, or furniture terms selectively impaired!

Priming

Task: Is this a word in English? Press button for "yes" or "no" as quickly as possible.

NURSE

DRAGE

CAT

TEF

 

DOCTOR ... NURSE

DOG .... CAT

Looking up a word in the mental dictionary primes semantically related words. i.e. People are faster to judge that NURSE is a word of English if they have just read DOCTOR. This is understood to mean that looking up DOCTOR in the mental dictionary makes it easier to look up NURSE. Similar finding for DOG and CAT and thousands of other related words.

Conclusion from this: mental dictionary is semantically organized

Conclusion

Mental dictionary contains:

• morphemes
• rules for combining morphemes
• non-productive and non-predictable complex words

Organization:

• not organized in single list
• organized according to phonological and semantic properties
