Lecture 3: Morphology I

[Note: these are lightly edited versions of overheads and notes used in class. They are provided in order to help you study, but they are not a substitute for coming to class and being prepared. The notes are incomplete, and will often be hard to make sense of if you were not in class.]

1. Entries in the Mental Dictionary

In morphology we're interested in finding out what we know about words and how to construct them. Put another way, what we're interested in is what is in the "dictionary" in everybody's head. Does it have the same kind of information and the same organization that you find in printed dictionaries like Websters, or does it look rather different?

First try... "Mental dictionary contains words you've heard (or read) before."

But this isn't enough, because it fails to account for our ability to easily understand (and create) words that we have never heard before.

Here are some words you've (probably) never heard or read before. They're no problem to understand.

rapability
crimsonish
unimpeach
googolbyte (you'll understand this one if you've read the chapter on Morphology in the textbook)

Here are a couple of words that you've never heard before, because they're made-up nonsense words. But you have no problem figuring out the plural form (if I tell you they're nouns) or the past tense (if I tell you they're verbs).

dax (plural: daxes; past tense: daxed)
bingle (plural: bingles; past tense: bingled)
riffett (plural: riffetts; past tense: riffetted)

Second try... "Mental dictionary contains all the words you know (previously and not yet heard)"

But this won't do either, because people can know more words than they could likely ever store in their heads.

Verbs in Spanish: 40+ forms per verb

entrar 'to enter'
1sg: entro (present tense)
2sg: entras
3sg: entra
1pl: entramos
2pl: entrais
3pl: entran
 
6 person/number forms per verb, for each of 7 tenses = 42 forms per verb,

Verbs in Nimboran (Papua New Guinea): 25000+ forms per verb

Nimboran is a language which can combine many morphemes to form complex words, like the following:

"ngeguomansedam"
'You and I will draw from here to there'

This word may be broken down into pieces as follows:

ngeduo - man - se - d - am
draw-incl.dl.subj-7loc-fut-inc

And here is a (partial, approximate) list of the available inflectional distinctions for verbs in Nimboran. Note that this language is not especially exotic - we find very many languages with similar properties.

4 tenses: future, present, recent past, distant past
5 persons: 1st, 2nd, 3masc, 3fem, Inclusive 3 numbers: singular, dual, plural
15 locations: above, below, there, far away etc.
2 aspects: repeated, not repeated
subject agreement, object agreement

A rough calculation of the number of forms that this allows per verb yields the following. This would mean that a speaker who knows one thousand verbs (a very low figure) would need to store 27 million verb forms in his mental dictionary - unlikely!

4 x 5 x 3 x 15 x 2 x 5 x 3 = 27,000

Third try... "Mental dictionary contains meaningful word-pieces a.k.a. 'morphemes'"

dog
cat
velociraptor
un-
-able
-ity
-ish

But just listing these morphemes in the mental dictionary is not enough. We need to explain why we can't make morpheme combinations like the following:

*run-ity
*funn-er
*disantimentestablishismarian

Fourth try... "Mental dictionary contains morphemes and instructions for combining them"

 

2. Information about how morphemes are combined

a. Bound vs. Free morphemes

Free

run
cat
computer

Bound

-ed
-ness
-ment
-couth (in fact, this seems to be a free morpheme for most class members)
-kempt
-shevelled

b. Affixes

Prefix

un-
pre-

Suffix

-ness
-er
-able

Infix

Bontoc (Philippines) fikas 'strong' fumikas 'to be strong' kilad 'red' kumilad 'to be red' fusul 'enemy' fumusul 'to be an enemy'
 fikas 'strong' fumikas 'to be strong'
kilad 'red' kumilad 'to be red'
fusul 'enemy' fumusul 'to be an enemy'
English 'expletive insertion' (substitute your own expletive for 'bloody')
fanbloodytastic
Villabloodynova
armabloodydillo

Circumfix

Chickasaw (Oklahoma) chokm+a ik+chokm+o 'he is good' 'he isn't good' lakn+a ik+lakn+o 'it is yellow' 'it isn't yellow' tiww+i ik+tiww+o 'he opens (it)' 'he doesn't open it'
 chokm+a 'he is good' ik+chokm+o 'he isn't good'
lakn+a 'it is yellow' ik+lakn+o 'it isn't yellow'
tiww+i 'he opens (it)' ik+tiww+o 'he doesn't open (it)'

c. What category are the combined morphemes?

head-strong (A)
water-tight (A)
pick-pocket (N) dare-devil (N)
over-test (V)
out-perform (V)
exact-ly (Adv)
sordid-ly (Adv)
happi-ly (Adv)
sing-er (N)
fight-er (N)
indemnifi-er (N)

Right-head rule (English)

"In a morphologically complex word, the rightmost morpheme determines the category of the word."

A problem with prepositions: Words containing prepositions are never prepositions

over-take (V)
hanger-on (N)
sun-down (N)
under-take (V)
after-birth (N)
down-fall (N)
up-lift (V)
fall-out (N)
work-around (N)
go-between (N)

Explanation: prepositions are closed class words

d. Open and closed class items in mental dictionary

Open Class

nouns
verbs
adjectives

Closed Class

prepositions
determiners (the, a)
inflections (-s, -ing, -ed)

Open vs. Closed class: neurological evidence

Broca's aphasia

Production:

"Well ... front ... soldiers ... campaign ... soldiers ... to shoot ... well ... head ... wound ... and hospital ... and so ..." (soldier describing how he was wounded)

Comprehension:

1. He showed her baby pictures. (ambiguous for all English speakers)
2. He showed her baby the pictures. (unambiguous for normal English speakers, ambiguous for many Broca's aphasia patients)
3. He showed her the baby pictures. (unambiguous for normal English speakers, ambiguous for many Broca's aphasia patients)
