Straight razor, one-speed bike, conventional warfare, acoustic guitar, bar soap Classify the following antonyms as complementary, gradable or relational opposites Good-bad, expensive-cheap, parent-offspring, beautiful-ugly, false-true, pass-fail, hot-cold, legal-illegal Think of five or more heteronyms
4
Review: Phrasal meaning
What does the principle of compositionality state?
5
Review: Meaning of nouns
What is it important to identify the head of a phrase? What do you know of the meaning derived from adjective-noun combinations? What do you know about the meaning derived from noun-noun compounds?
6
Review: Sense and reference
What is sense and reference? Do all nouns have both sense and reference? Give examples.
7
Review: Sense and reference
In a conversation about Britain in 1982 can the Prime Minister and the Leader of the Conservative Party have the same referent? If we are talking about a situation in which John is standing in the corner, can John have the same referent as the person in the corner?
8
Review: Sense and reference
Do the following words refer to things in the world? Almost, probable, and, if When you look up the meaning of the word in a dictionary what do you find? Its referent? An expression of the same sense? Sense is hard to define. It’s easier to talk about words that have the same sense in order to understand sense.

10
Verb meaning The verb determines the number of objects
It constrains the semantic properties of both the subject and the object(s) Examples?
11
Thematic roles Subjects and objects of verbs are semantically related to the verb.
12
Thematic roles The boy found a red brick Agent: the boy
Theme: a red brick Part of the meaning of find is that the subject is an agent and the object a theme.
13
Thematic roles John put the red brick on the wall. Agent: John
Theme: the red brick Location: on the wall
14
Thematic roles Mary received a gift from John Source: John Goal: Mary
Theme: a gift
15
Thematic roles John cut his hair with a razor. Agent: John
Theme: his hair Instrument: with a razor
16
Thematic roles John admires Mary Experiencer: John Stimulus: Mary
17
Thematic roles in other languages
German does not allow location to be the subject of a clause. This hotel forbids dogs In diesem Hotel sind Hunde verbotem (in this hotel are dogs forbidden) Thematic roles are often referred to as ‘case’ of the noun In Finnish, the morphological shape of the noun reflects its thematic role Languages with a rich case system often put more constraints on the thematic role that’s permitted in subject position
18
The theta-criterion The process of assigning thematic roles is called theta assignment. E.g., The boy opened the door with the key Theta assignment: Agent=the subject Theme=the direct object Instrument=the prepositional phrase Theta criterion: states that a particular thematic role may occur once in a sentence *The boy opened the door with the key with a lock-pick
19
The semantic relations between verbs and noun phrases are part of linguistic competence and account for much of meaning in language.
20
Sentential meaning Like noun phrases sentences can have sense or intension Sentences can also have reference or extension Their extension is true if the sentence is true, false if the sentence is false
21
Sentence meaning Truth conditions
The sense of a declarative sentence makes it possible to know under what circumstances the sentence is true These circumstances are the truth conditions of the sentence The truth of falsehood of sentences is their reference/extension
22
Sentence meaning Truth conditions
Knowing the truth conditions is not the same as knowing the facts The truth conditions let you examine the world and learn the facts You may not know the truth of ‘The Mecklenburg Charter was signed in 1770’ But if you know its meaning you know how to discover its truth
23
Sentence meaning Truth conditions
E.g. Rufus believes that the Declaration of Independence was sign in 1976 An entire sentence maybe true even if one or more parts are false The example is true if some individual named Rufus believe the statement
24
Paraphrase Two sentences are paraphrases if they have the same truth conditions, i.e. whenever one is true, the other is true too The horse threw the rider. The rider was thrown by the horse.
25
Paraphrase Not all active-passive pairs are paraphrases
Every person in this room speaks two languages Two languages are spoken by every person in this room These two sentences do not have the same truth conditions
26
Entailment Sometimes knowing the truth of a sentence entails or necessarily implies the truth of another sentence Corday assasinated Marat Marat is dead Much of what we know about the world comes from knowing the entailments of true sentences
27
Contradiction Contradiction is negative entailment Scott is a baby
Scott is an adult
28
Events and states Some sentences describe events such as
John kissed Mary John ate oysters Other sentences describe states such as John knows Mary John likes oysters These differences have syntactic consequences
29
Events and states Compare With Mary was kissed by John
John is kissing Mary Kiss Mary! John deliberately kissed Mary With ? Mary is known by John ? John is knowing Mary Know Mary! John deliberately knows Mary
30
Pronouns and coreference
Show the close interaction of sentence structure and semantics Reflexive pronouns pick an antecedent from the same S or phrase Compare: Jane bit herself * Jane said that herself slept
31
Pronouns and coreference
Sentence structure plays a role in the interpretation of pronouns Compare John believes that he is a genius He believes that John is a genius It’s not about linear order The fact that he is considered a genius bothers John
32
Anomaly Anomaly occurs in many ways
Contradictory semantic properties Nonsense words Violation of semantic rules… The fact that we are able to understand anomalous sentences and identify them as such is evidence of our knowledge of the semantic system of a language
33
Anomaly Sometimes breaking semantic rules is done intentionally to create special effects, as in poetry …children building this rainman out of snow (e.e. cummings) … a grief ago (Dylan Thomas)
34
Metaphor A metaphor is an expression that ordinarily designates one concept, used for another The fall of the empire Walls have ears Dr. Jekyll is a butcher Time is money To understand metaphors we need to understand both the literal meaning and facts about the world Metaphor can have a strong cultural component My car is a lemon
35
Idioms The principle of compositionality is sometimes supeseded by expressions that seem decomposable Idioms are similar in structure to ordinary phrases but have frozen meaning Bite your tongue Kick the bucket Give a piece of your mind Paraphrases often do not retain the idiomatic meaning but there are exceptions The FBI kept tabs on radicals Tabs were kept on radical by the FBI
