2What is language?With a partner, try to come up with a definition of what language is!
3Some definitions of Language Sapir: “a purely human and non-instinctive method of communicating ideas, emotions and desires by means of voluntarily produced symbols.”Bloch & Trager: “a system of arbitrary vocal symbols by means of which a social group cooperates.”Hall: “the institution whereby humans communicate and interact with each other by means of habitually used oral-auditory arbitrary symbols.”Chomsky: “a set (finite or infinite) of sentences, each finite in length and constructed out of a finite set of elements.”Sapir 1921: “Language is a purely human and non-instinctive method of communicating ideas, emotions and desires by means of voluntarily produced symbols.”(Not broad enough; language communicates more than this. Too broad, incudes all kinds of gestures and other symbols which aren’t language.)Bloch and Trager 1942: “A language is a system of arbitrary vocal symbols by means of which a social group co-operates.”(Narrowly focused on social functions)Hall 1968: Language is “the institution whereby humans communicate and interact with each other by means of habitually used oral-auditory arbitrary symbols.”Robins 1979 avoids a formal definition because they “tend to be trivial and uninformative , unless they presuppose ... some general theory of language and of linguistic analysis.”Chomsky 1957, Syntactic Structures: “From now on I will consider a language to be a set (finite or infinite) of sentences, each finite in length and constructed out of a finite set of elements.”Covers more than just natural languages, but all natural languages meet the definitionNot only are there structural properties in language, but they are so abstract, so complex and so highly specific to their purpose that they couldn’tbe learned from scratch by an infant grappling with the problem of acquiring his native language = innate to human brainFocuses on the purely structure propeties of languagesopen-ended, arbitrary symbol systems
4Some definitions of Language The commonly accepted definition: “Language is a system of arbitrary vocal symbols used for human communication.”I like this one:A system that uses some physical sign (sound, gesture, mark) to express meaning.
5Language vs communication • Language is not identical with communication• There are many other communicative tools such as– Turn-taking– Intonation– Gesture (body language)– Eye gaze control– Touch– Displays: external objects, including jewelry, tattoos, clothing, cars

8Where does language come from? Old Theories:1. Bow-Wow Theory: Speech arose through imitation of environmental sounds, such an animal calls.Evidence: Use of onomatopoeic words like “hiss”, “knock knock”, “cuckoo”, “wuff” etc.
9Where does language come from? Old Theories:2. Pooh-Pooh Theory: Speech arose through people making instinctive cries, such as those caused by pain or other emotions.Evidence: Universal use of sounds as interjections.
10Where does language come from? Old Theories:3. Ding-Dong Theory: Speech arose because people reacted to stimuli in the world around them, spontaneously producing sounds (“oral gestures”) in response to them.Eg: mama or some similar-sounding word referring to mother; sound of [m] could result from approximation of lips while nursing.
11Where does language come from? 4. Yo-he-ho Theory: Hypothesizes that when people work together, their physical efforts promote communal rhythmic grunts, leading to chants, leading to language.Evidence: Universal use of prosodic features in language, esp. rhythm (like stress or accent).
12Newer Theories 1. Speech-Based Theory Evolution led to restructuring of vocal tractBig change: descent of the larynx (larynx much higher in other animals), which produces a larger throat cavityLarger throat cavity useful in making a wide variety of vowel soundsNote: Some studies have found that mammalian larynx placement is much lower during vocalizations (“dynamic descent of the larynx”), yet non-human mammals still can’t produce the variety of sounds that humans can.Some animals have immense vocal range (cf. birds, esp. parrots), but still cannot speak
13Newer Theories 2. Intelligence-Based Theory Increased brain size led to increased ability for symbolic thoughtSymbolic thought led to symbolic communicationSymbolic communication endows humans with decided survival advantage (cooperation, planning, etc.)
14Newer Theories 3. Protolanguage theory The first linguistic systems were extremely rudimentary, gradually developed greater complexityProtolanguage: Basically limited to nouns (“object-names”) and verbs (“action-names”); supported by some simple ordering requirements.Essentially no grammar.
15Newer Theories 4. The Cognitive Theory The ability to understand the world well enough to figure out ways of manipulating it to outsmart other plants and animals. Several things evolved at the same time to support this way of life.a) Cause-and-effect intelligence: E.g. How do sticks break, how do rocks roll, how do things fly through the air?b) Social intelligence: How do I coordinate my behavior with other people so that we can bring about effects that one person acting alone could never have done?c) Language: If I learn something, I don't get the benefit of it alone, but I can share it with my friends and relatives, I can exchange it for other kinds of commodities, I can negotiate deals, I can gossip to make sure that I don't get exploited.
16What knowledge do you need to know about language? Words –morphologyWord order-syntaxMeaning- semanticsInterpretation of situations –pragmaticsHow much of the above do you need to know in order to be able to learn a language?
17What do linguists do? They don’t necessarily “learn languages” Many linguists can only speak their native language.They are often interested in the structure of languages. They mightspecialize in one language, or a group of languagescompare different languagesstudy features shared by all languagesMany linguists study speech sounds, and grammar

19Linguistic Competence vs. Linguistic Performance
21Linguistic competence What we know when we ‘know’ a language.This knowledge is largely unconscious.Peter and Sally are going to the cinema.Knowledge does not automatically guarantee performance...
22Linguistic Performance Performance is your real world linguistic output. Performance may accurately reflect competence, but it also may include speech errors due to slips of the tongue or nervousness.
23Linguistic Knowledge vs. Linguistic Performance There’s a distinction betweenWhat you know about “correct” and “incorrect” languageYour ability to always produce “correct” sentences.
24Language competenceLinguistic competence develops through language use.Proficiency: development of language competence through language use.Basic language use skills:Speaking, listening, reading and writing
