Questions… ? Semantics -- LIN1180

Part 1 What is semantics? Semantics -- LIN1180

Some things we know These sentences describe the same situation: The small blue circle is in front of the square. The square is behind the small blue circle. We are also capable of verifying that both sentences are true in this particular situation. This is because we know what the world must be like in order for these sentences to be true. Semantics -- LIN1180

Some things we know We know that the following sentence can mean more than one thing (it is ambiguous): She drove past the bank. This seems to be related to our knowledge of what bank denotes. Semantics -- LIN1180

Some things we know We also know that sentence two follows from sentence 1 (technically: sentence 1 entails sentence 2) John murdered the president. The president is dead. In this particular case, it seems to be related to the meaning of murder. Semantics -- LIN1180

Semantics Usually defined as that part of Linguistics that deals with meaning word meaning sentence meaning The remainder of this lecture will try to outline: Why this is of interest to the linguist What problems arise with this enterprise Semantics -- LIN1180

Grammar Grammar (in the linguist’s sense) is a characterisation of the knowledge of a speaker/hearer. We ask: when a speaker “knows” a language, what does she know exactly? The linguist’s task is therefore to characterise what it takes for a speaker/hearer to produce and comprehend her language. Semantics -- LIN1180

Semantics as part of grammar Semantics is part of a speaker’s (listener’s) linguistic knowledge. Therefore, semantics is part of grammar. Speakers have some internalised knowledge such that: They understand what other people mean They are able to say what they mean Semantics -- LIN1180

Knowledge of language is productive Open any book… How many of the sentences in it have you seen/heard before? Some, but certainly not all of them. But even if the sentences are completely “new”, you are still able to understand them. To characterise our knowledge of language, we need to characterise this ability people have to decode any new utterance, so long as it conforms to the grammar of their language. Semantics -- LIN1180

The problem of knowledge Chomsky (1986) identified this as Plato’s problem: A lot of what we hear or say is new How do we manage to understand and produce such an infinite variety of things, even if we’ve never heard them before? This is the basic motivation for much linguistic work since the 1950’s. Semantics -- LIN1180

The problem of knowledge Until the 1960s, the role of semantics in grammar was somewhat obscure. What can semantics contribute which is not accounted for by other areas? syntax (phrase structure) morphology (word structure) phonology (sound structure) … Semantics -- LIN1180

Katz and Fodor (1963) an early attempt to characterise what is required of a semantic theory “semantics takes over the explanation of the speaker's ability to produce and understand new sentences at the point where grammar leaves off” (p. 172-3) K&F argued that syntax and phonology alone cannot give a full account of a speaker’s knowledge of language e.g. the sentences the man bit the dog and the dog bit the man are structurally identical, but differ in meaning (NB: K&F assume that syntax has no bearing on meaning as such) Semantics -- LIN1180

Language and the world But in characterising knowledge of meaning, we also have the problem of distinguishing linguistic knowledge from world knowledge E.g. What is the meaning of the word man or ostrich? Is your knowledge of the meaning independent of your experience of the world? Are you born with an innate knowledge of such words? Semantics -- LIN1180

Knowledge of language and the world semantics How do we account for the relationship between words and concepts? How do we decode the meaning of complex sentences? How is linguistic meaning related to the world? concepts/ thoughts things & situations Semantics -- LIN1180

Knowledge of language and the world How do we account for the relationship between words and concepts? How do we decode the meaning of complex sentences? How is linguistic meaning related to the world? lexical semantics sentential semantics lexical semantics & sentential semantics Semantics -- LIN1180

The problem of knowledge In designing a semantic theory, we need to account for productivity We know a lot of words (thousands) and their meanings. This is our mental lexicon. We can create an infinite number of sentences, using grammatical rules of our language. The meaning of sentences is derived from the meaning of their component words and the way they’re combined. Semantics -- LIN1180

Compositionality The guiding principle to explaining the productivity of meaning is the Principle of Compositionality The meaning of a sentence is a function of the meaning of its component words and the way they’re combined. Often attributed to the philosopher Gottlob Frege. Semantics -- LIN1180

Part 2 Semantics in relation to other components of grammar Semantics -- LIN1180

Meaning and grammar (I) In some theories, such as Generative grammar, the language faculty is divided into modules: This view emphasises distinct roles played by different components. There is a separate component for meaning, completely unrelated to syntax or phonology. phonology syntax semantics Semantics -- LIN1180

Is this view tenable? It seems clear that some grammatical facts must take meaning into account. Jake opened the door. The door opened. The girl kissed Steve. ?Steve kissed. It looks like the meaning of the verbs affects their syntactic behaviour! Open is a change of state verb. Kiss is not a change of state verb. Semantics -- LIN1180

Meaning and grammar (II) An alternative view, found for example in Cognitive Grammar, argues that meaning is inseparable from the other components. In this framework, people often argue also that linguistic knowledge and encyclopaedic knowledge cannot be separated. phonology syntax semantics Semantics -- LIN1180

Part 3 What should a semantic theory look like? Semantics -- LIN1180

You made great black coffee. An example situation So did you like the food? You made great black coffee. Semantics -- LIN1180

Requirements for our theory (I) What kinds of knowledge do you need to understand a reply such as you made great black coffee: Word meaning: black, coffee, great, make Phrasal and sentence meaning (Compositionality): black + coffee (great + black + coffee) + (make + PAST) Semantics -- LIN1180

Requirements for the theory (II) You also need to consider contextualised meaning: The pronoun you means person of unspecified gender whom the speaker is addressing Only makes sense in a context where there is an interlocutor Semantics -- LIN1180

A first attempt The task: The solution (take 1): Design a theory that will explain a speaker’s semantic knowledge, i.e. Word meaning Sentence meaning … The solution (take 1): Suppose we just claimed that meaning is about knowing “dictionary definitions” Semantics -- LIN1180

Problem 1: Circularity Knowing the meaning of a word = knowing the definition E.g. coffee = a beverage consisting of an infusion of ground coffee beans We need to know the meaning of the words making up the definition (infusion, coffee beans)! This involves giving further definitions… Where would this process stop? The problem here is trying to define word meaning using other words… Semantics -- LIN1180

Problem 2: World knowledge vs. Linguistic Knowledge Suppose you think of coffee as: black, hot, bitter… Suppose I think of coffee as: black, hot, ground from coffee beans, grown in Brazil… Which of the two conceptions is correct? Which of these aspects belongs to language, and which are “encyclopaedic knowledge”? How much do we need to agree on in order to understand each other’s uses of the word? Semantics -- LIN1180

Problem 3: Individual differences Suppose we agree that coffee is typically black. We might not agree precisely on the true meaning of the word black: How dark must something be to qualify? When does black become dark brown? People often differ on the boundaries This doesn’t seem to stop them understanding each other Two possible goals of a semantic theory: to identify aspects of meaning independent of individual variation to account for how speakers manage to understand each other even where there is such variation Semantics -- LIN1180

Interim summary Thinking of meaning as “definition” is problematic because: Definitions are linguistic, and so their components will themselves need definition. Therefore, we need to try to formulate our account of meaning without recourse to words. People won’t necessarily agree on definitions. Semantics -- LIN1180

The need for a metalanguage To meet these problems, we need to characterise linguistic meaning independently of words: This involves using a semantic metalanguage A way of “translating” meaning into a form that is language-neutral. We might assume that speakers have a stock of concepts in their heads E.g. the meaning of coffee is the concept COFFEE The concept is not tied to its “English” usage. A Maltese speaker has the same concept when she uses kafé Such concepts might be argued to exist in a speaker’s mental lexicon Semantics -- LIN1180

Problem 4: Context The phrase you made great black coffee seems to acquire new shades of meaning in different contexts: You’re a hopeless cook, but at least, the coffee was OK… You completely failed to impress me… Are such context-dependent effects part of semantics? Semantics -- LIN1180

Semantics vs. pragmatics Many linguists make a distinction between Literal/conventionalised meaning “core meaning”, independent of context This belongs to semantics proper Speaker meaning & context What a speaker means when they say something, over and above the literal meaning. This and other “contextual” effects belong to pragmatics NB. The distinction between semantics and pragmatics is not hard and fast Is the context-dependent meaning of you a matter for semantics or pragmatics? Semantics -- LIN1180

Summary Semantics is part of linguistic knowledge This is productive and systematic Compositionality of meaning helps us to explain how people can interpret a potentially infinite number of sentences Theories of linguistic meaning must account for distinctions between: Linguistic knowledge and world knowledge Literal meaning vs contextualised or non-literal meaning Semantics -- LIN1180

Next lecture Mainly introducing some of the core concepts that semanticists use in their analysis: Utterances vs sentences vs propositions Sense and reference Semantics -- LIN1180
