Review
Meaning is arbitrary
There is no relationship between the sounds associated with a word and the
physical object or action that the word signifies.
Denotation: the literal meaning of a word; its dictionary definition.
Connotation: Associations or the emotional suggestions related to a word
Sense relations:
In semantics we consider sense relations i.e. how the meanings of words and
phrases relate to the meanings of other words and phrases.
Synonymy
Synonym: Two or more expressions share a similar meaning
Testing for Synonymy
The substitution test
If two words are synonyms, then one should be able to replace the other in a
sentence, without changing the sentence’s meaning.
Leonardo looked / glanced / stared / gazed at the Mona Lisa
Do synonyms have exactly the same meaning?
The thief tried to hide / conceal the evidence
Then he tried to hide
*Then he tried to conceal
Leonardo gazed at the Mona Lisa for an hour
?Leonardo glanced at the Mona Lisa for an hour
Entailment
The principle that under certain conditions the truth of one statement ensures
the truth of a second statement.
Synonymous: two–way entailment
If I hide something, I conceal it
Inclusive meaning: one–way entailment
If I incinerate something, I destroy it but
If I conceal something, I hide it.
If I destroy something, I do not
necessarily incinerate it.
Words may have no entailment
If I burn something, I do not necessarily destroy it
If I destroy something, I do not necessarily burn it
Inclusive meaning: one–way entailment
Notice
destroy is a general term
(end the existence of something)
incinerate is more specific (destroy by burning)
In this context, incinerate and destroy display one–way entailment. incinerate is
just one of many ways to destroy something e.g.
blow up, melt down, incinerate, smash to pieces, level, raze etc
Hyponymy
When one word includes the meaning others, the relationship is referred to as
hyponymy.
We call the more specific term a hyponym of the more general term
incinerate is a hyponym of destroy
Exercise
Arrange the following sets of words from general to more specific.
(a) mouse, rodent, mammal, rat
mammal > rodent > rat, mouse
(b) house, building, bungalow, structure, cottage
structure > building > house > cottage, bungalow
(c) aunt, person, relative, female, cousin
person > relative > female > aunt
cousin
Labelling and diagramming hyponymy
The more general or more inclusive term
= superordinate
The more specific term
=
Two or more hyponyms of the same superordinate
= co–hyponyms
superordinate
hyponym
hyponym
cat
cheetah
lion
leopard tiger
co-hyponyms
All words can be either the superordinate or a (co)hyponym of another word or
phrase
domesticated animals
cat
dog
horse
Testing for hyponymy: The ‘is a type of’ test
We can identify the superordinate term by using the ‘is a type of’ test
pinot, sauvignon, wine, chardonnay
Wine is a type of chardonnay / pinot / sauvignon?
No
Chardonnay / pinot/ sauvignon are types of wine?
Yes
superordinate
co-hyponyms
wine
pinot
Sauvignon
Chardonnay
Exercise
Use the ‘is a type of’ test to identify the superordinate terms in the following
lists:
(a)
beagle, poodle, dog, terrier, retriever
(b) salmon, cod, snapper, fish, shark
(c)
diamond, ruby, gemstone, sapphire, granite, emerald, stone
Draw a tree for (c)
stone
gemstone
granite
diamond ruby sapphire emerald
Exercise
Complete the following sentences using the same word for both
Fred’s eyes recovered and he slowly regained his sight.
Lake Wakatipu is a magnificent sight.
Clearly, both uses of ‘sight’ derive from ‘see’. However, despite their clear
semantic relationship to each other, they do not mean the same thing.
a. ‘the faculty or power of seeing’
sight
b. ‘places of interest in a city, town, or other place.’
Polysemy
A single word with more than one meaning is polysemous. In the context above,
‘sight’ is polysemous.
Identifying polysemy
Polysemous words are easy to identify
use the dictionary!
music (n.) (i.) sound produced by means of instruments; kind of art form
(ii.) particular style of that art form (e.g., baroque music)
Exercise.
Are the following polysemous?
hand
body part, clock, a round of applause, someone’s writing etc.
wood
stick, building timber, small group of trees
child
young person, an immature or inexperienced person of any age
crane
machine, bird (yes, they are related)
Consider the highlighted words in the following sentences:
(A)
(B)
a) The ships are listing badly.
We are listing all members of the society.
b) The statue is made of lead.
The dog is on his lead
c) Bus fares have just gone up.
Bus fairs are where you buy buses.
Are the highlighted words examples of synonymy?
polysemy?
They are neither!
Although the (A) and (B) words look the same, sound the same or both
They are not semantically related to each other
They cannot be substituted for each other
Homonymy
Words that look and/or sound the same, but have no other semantic relationship,
are said to be homonymous
Homonymy
Homonyms: the written and spoken forms are identical
bank
bank
lie
lie
bat
bat
Homographs: only the written forms are identical
lead = metal
[led]
lead = leather strip used when walking a dog
[li:d]
row [ɹou] [ɹau]
use [ju:s] [ju:z]
Homophones: only spoken forms are identical
tail tale [teiɫ]
to too two [tu:]
flour flower [flauwə]
Antonymy
The semantic relation that holds when two words express opposite meanings
Complementary opposites
The presence of one quality or state signifies the absence of the other and vice
versa. There is no halfway point.
alive / dead
present / absent
married / single
If A is true, then B cannot be true
equally
The tree is alive
=
The tree cannot be dead
The tree is dead
=
The tree cannot be alive
Note: ‘the tree is half dead’ = it is still alive
Multiple complementary opposites
A subcategory of complementaries which are found in sets
days of the week,
months of the year, signs of the Zodiac
etc.
Gradable opposites
There is a gradual transition along a scale between to points
hot
⇦
Other examples:
warm
tepid
cool
cold
⇨
big
small
heavy light
fast
slow
Gradables can be marked for comaprative and superlative degrees
bigger
biggest
more beautiful
most beautiful
Gradable opposition is relative to the object described e.g. a small elephant is
bigger than a large mouse
The use of gradable antonyms
In each pair one of antonyms, one is the marked term and the other unmarked.
one term of the opposition is the broader, dominant one.
Unmarked
How tall are you?
How old are you?
There is no implication in the questions that the you are particularly tall or old.
The questions simply ask for the degree of the gradable quality.
Marked
How short are you?
How young are you?
On the other hand, these questions imply that the person is actually short or
young.
Relational opposites
The opposition requires the context of a relationship between the two meanings.
If A is B’s
, then B must be A’s
parent
child
employer
employee
If A
’s to / from B, then B must
give
receive
buy
sell
borrow
lend
to / from A

Noun-centred meaning
Nouns are often 'modified' by other words. The meaning of a noun is built up of
the meanings of the noun and its modifiers.
two cars
An adjective more closely delimits the kind of entity referred to by the noun
cold water
a false friend
Semantic properties control the types of modifiers
have a cat
*have a toast
*much cat
much toast
A number of cats
*A number of toasts
*The amount of cat
The amount of toast
The amount of cat in my hamburger was inadequate
?The amount of cats in Gareth Morgan's neighbourhood has decreased
Verb-centred meaning
Verbal features, like noun features, also have syntactic effects
verbs: events, actions, states etc
In English, ‘syntax’ says a noun is required before the verb, but optionally after
the verb
Cats eat mice
The mouse worries.
This is not a random, speaker choice; it is controlled by the properties of the
verb
*John resembles.
*Mary disappeared the cat.
John resembles the cat
Mary disappeared
Eventives
eat, run, jump, fly, measure , give etc
Statives
know, like, be, seem, appear, resemble etc
John eats alligator meat
John is eating alligator meat
John likes alligators
?John is liking alligators
Alligator meat is often eaten by John
Eat the alligator meat, John!
?Alligators are like by John
?Like alligators, John!
Other verb features
*John thinks that he will ever eat alligator again
John does not think that he will ever eat alligator again
John despairs that he will ever eat alligator again
John doubts that he will ever eat alligator again
This suggests that some verbs have ‘built in’ negation features and do not
require the presence of not
Verb control
The cat eats
Subject Verb
the mouse
Object
Verbs typically require that the subject refer to a particular kind
of entity
to laugh
The woman
?The ghost
laughs
*The brick
There is a semantic relationship between the kinds of noun that
a verb requires and the verb itself. We call the semantic
relationship the thematic role a verb assigns to a noun.
Thematic roles ( Ɵ-roles )
1. If an entity performs the action denoted by the verb AND the entity has volition
(the ability to decide to do the action or not) = agent
Joan /the girl / she sang
agent
Are the following highlighted phrases agents?
The concrete cracked
The apple was eaten by the boy.
2. If an entity undergoes or is affected by the action denoted by the verb =
theme
The girl moved the toy / the chess piece / the chair
agent
theme
Are the following highlighted phrases themes?
The painting was done by the old artist
Mary sent her friend an apple
NOTE: Thematic roles DO NOT depend on a phrase’s position
The toy was moved by the girl
theme
agent
Other thematic roles
Goal
the place to which an event is directed
I shifted the chair to the wall.
Location
the place where an event takes place:
He is working in the kitchen.
Source
the place where an event originates:
She drove up from Wellington.
Instrument
The means by which an action is performed
Brian’s clone hit his car with a rock.
Experiencer
an animate entity that perceives something, is aware of something,
psychologically or emotionally
She worries a lot.
Stimulus
that which causes an entity to perceive something, be aware of something,
psychologically or emotionally
The spider frightened the girl.
Causative
a natural force that causes an event to happen
The cyclone destroyed the village.
Possessor
an entity that owns or has another entity in its possession
Bill's best friend has gone away.
If two sentences are paraphrases of each other, that is, if they have the same
meaning, the corresponding noun phrases have the same thematic relations
The dog chased Jane vs. Jane was chased by the dog
agent
theme
theme
agent
Sentences that are not paraphrases can be thematically similar, even though the
meanings are not the same
The boy opened the door with the key
agent
theme instrument
The key opened the door
instrument
theme
The door opened
theme
Notice English uses prepositions to indicate certain thematic roles:
in, on, at
to
from
with
to talk about locations
to indicate goals
to indicate sources
to indicate instruments, possession
Restrictions on thematic roles (the theta-criterion)
As we saw, once a role is assigned it cannot be changed, but also note that no role
can be assigned more than once in a sentence
*I opened the door with the key with the crowbar
*The girl the boy played the piano the violin
Exercise:
In the following sentences, identify the thematic role of each NP
Roles: agent, theme, causative, experiencer, stimulus, source, goal,
location, instrument
agent
