费马定理证明过程全文共四篇示例，供读者参考第一篇示例：费马定理是数论中的一个重要定理，由著名数学家费马在17世纪时提出并据一直引起数学界的广泛关注和研究。
费马定理又称费马大定理，其表述为：对于大于2的正整数n，不存在三个正整数a、b、c，使得满足a^n + b^n = c^n。
费马定理证明的过程是一个漫长而又复杂的数学推理过程，而直到1995年，英国数学家安德鲁·怀尔斯才最终给出了费马定理的证明。
费马定理的证明历经了数百年间许多数学家的探索和努力，费马本人曾在他的笔记本上写下了：“我找到了这个证明，但是这个空间太小，无法容纳这个证明。
”这句话也在一定程度上激发了后世数学家对这个问题的研究和探索。
费马定理的证明过程可以大致被分为三个阶段，分别是费马猜想的提出、证明的辅助工具的建立、以及最终的证明。
费马猜想的提出发生在17世纪，费马在一个边注中提出了这个猜想，称其为“我无法证明的定理”，这也给后世数学家提供了一个极大的挑战。
费马猜想的提出激发了许多数学家的研究热情，这个定理的证明一度被认为是不可能的。
随后的数百年间，许多数学家纷纷投入到费马定理的研究之中，他们提出了许多有关费马定理的猜想和假设。
于是，证明费马定理的难度立即从退化为一个普通的数学难题而变得异常复杂。
在费马定理的证明中，数学家们创立了许多重要的数学概念和工具，例如椭圆曲线、调和模形式等，这一系列的辅助工具为费马定理的证明提供了坚实的数学基础。
这些独立的数学概念在费马定理的证明过程中发挥了至关重要的作用。
最终，英国数学家安德鲁·怀尔斯于1995年成功地证明了费马定理，这也为整个数学界带来了一场轰动。
怀尔斯的证明过程异常复杂，包含了许多高深的数学知识和技巧，这也是费马定理证明过程中最为汗牵动人心的部分。
通过费马定理的证明过程，我们可以看到数学家们在对一个数学难题进行探索和研究的过程中所需付出的辛勤努力和不懈追求。
费马定理的证明，实际上也反映了数学研究的艰辛和复杂性。

说明应许多教师和学生的要求，我们编写了本教科书每章后面的习题答案。
但是，有两点必须说明一下。
第一，对术语的定义或解释，多是以本书相关章节为依据，所以会有些局限性。
好在目前市场上有多种语言学词典，大家可参考其他定义和解释。
第二，对开放式问答题的回答，多为提示性的，而且也是基于本书内容做的基本回答，往往显得过于简略。
一方面，本书是入门性的教程，对诸多问题的讨论仍欠深入；另一方面，每章后面附的参考书，可以告诉读者到哪里去查找相关信息，加深对某个问题的了解。
总之，这里提供的答案是参考性的，绝不是唯一的，更不是穷尽一切的。
充其量，它只能给教师和同学提供一点点方便而已。
如发现不当之处，敬请指教。
Chapter 1Introduction1. Define the following terms briefly.(1) linguistics: the scientific or systematic study of language.(2) language: a system of arbitrary vocal symbols used for human communication.(3) arbitrariness: the absence of similarity between the form of a linguistic sign and what it relates to in reality, e.g. the word dog does not look like a dog.(4) duality: the way meaningless elements of language at one level (sounds and letters) combine to form meaningful units (words) at another level.(5) competence: knowledge of the grammar of a language as a formal abstraction and distinct from the behavior of actual language use, i.e. performance.(6) performance: Chomsky’s term for actual language behavior as distinct from the knowledge that underlies it, or competence.(7) stylistics: the study of how literary effects can be related to linguistic features.(8) phatic communion: Language is used to establish an atmosphere or maintain social contact between the speaker and the hearer.(9) functionalism: the study of the forms of language in reference to their social function in communication.(10) formalism: the study of the abstract forms of language and their internal relations.(11) synchronic linguistics: the study of language and speech as they are used ata given moment and not in terms of how they have evolved over time.(12) diachronic linguistics: the study of linguistic change over time in contrast to looking at language as it is used at a given moment.2. No, language is human-specific. Human language has seven design features, including arbitrariness, duality, productivity, interchangeability, displacement, specialization and cultural transmission. These features are found utterly lacking in dogs’ or pigs’ noises and thus set human language apart from animal cry systems.3. Arbitrariness refers to the fact that there is no logical or intrinsic connection between a particular sound and the meaning it is associated with. For example, for the same animal dog, in English we call it /d0g/, in Chinese as “gou”, but “yilu”in Japanese; it barks wow wow in English but wang wang in Chinese. Of course, onomatopoetic words such as “quack-quack” and “bang” are exceptions, but words like these are relatively few compared with the total number of words in a language.4. A human baby does not speak any language at birth. What language the baby is going to speak is determined by the culture he is born into. A Chinese baby born and brought up in London by an English family will speak English, while an English child brought up in Beijing by a Chinese aunt will speak Chinese. That is to say, language cannot be transmitted through heredity. It is culturally transmitted.5. Firstly, linguistics describes languages and does not lay down rules of correctness while traditional grammar emphasizes correctness. Secondly, linguistics regards the spoken language as primary, while traditional grammar emphasizes the priority of the written language. Thirdly, traditional grammar is based on Latin and it tries to impose the Latin categories and structures on other languages, while linguistics describes each language on its own merits.6. A descriptive approach attempts to tell what is in the language while the prescriptive approach tells people what should be in the language. Most modern linguistics is descriptive, whereas traditional grammars are prescriptive.7. Synchronic linguistics studies language at one particular time while diachronic linguistics studies language developments through time. Synchronic linguistics focuses on the state of language at any point in history while diachronic linguistics focuses on the differences in two or more than two states of language over decades or centuries.8. No, human language has the design feature of specialization. It refers to the fact that man does not have a total physical involvement in the act of communication. For example, a mother can tell a story to her child while slicing up a cake. However, wolves can only respond to a stimulus and is totally involved physically in the communication process. Thus, a wolf cannot have a language similar to man’s, even though it could express a thousand different emotions. Besides, the aspect of productivity also distinguishes human language from wolf ’s postures.Chapter 2The Sounds of Language1.Define each of the following terms briefly.(1) articulator: the tongue, lips, and velum, which change the shape of the vocal tract to produce different speech sounds.(2) assimilation: a phonological process whereby a sound becomes phonetically similar (or identical) to a neighboring sound, e.g. a vowel becomes [+nasal] when followed by a [+nasal] consonant.(3) consonant: a speech sound produced by partial or complete closure of partof the vocal tract, thus obstructing the airflow and creating audible friction. Consonants are described in terms of voicing, place of articulation, andmanner of articulation.(4) elision: the leaving out of a sound or sounds in speech.(5) intonation: the variation in pitch and stress which gives beat and rhythm to the tune the voice plays in ordinary speech.(6) phoneme: the abstract element of a sound, identified as being distinctive in a particular language.(7) phonetics: the study of linguistic speech sounds, how they are produced, how they are perceived, and their physical properties.(8) phonology: the study of the abstract systems underlying the sounds of language.(9) stress: the prominence given to certain sounds in speech.(10) voicing: the vibration in the larynx caused by air from the lungs passing through the vocal cords when they are partly closed; speech sounds are saidto be either voiced or voiceless.(11) voiceless: When the vocal cords are spread apart, the airstream from the lungs is not obstructed at the space between vocal cords and passes freely.The sounds produced in this way are described as voiceless sounds.(12) vowel: a speech sound produced without significant constriction of the air flowing through the oral cavity.2. Minimal pair test or substitution test.Minimal pair test or substitution test is to see whether substituting one sound for another results in a different word. If it does, the two sounds represent different phonemes. For example, as to the English word bear, if we substitute p for b, we get the word pear, the two are different words. Then /b/ and /p/ represent different phonemes. Other examples are chunk/junk, ban/bin, bet/beat, fine/vine, side/ site, etc.3. Take the word big for example, in the word big /big/, /b/ is the onset, /i/ is the nucleus and /g/ is the coda. The difference between open syllables and closed syllables is whether the words have codas. If there are codas, they are closed syllables,such as pig, hat and at; if not, they are open syllables, such as do, I, tea and key.4. (1) stop, consonant(2) back, rounded, vowel5. (1) voiceless / voiced(2) bilabial / labiodental(3) close / semi-open(4) stop / nasal(5) alveolar / palatal(6) alveolar / dental(1) kit/git, bucker/bugger, bag/back(2) mark/nark, smack/snack, sum/sun(3) best/vest, ober/over, lib/live(4) bore/more, abate/amate, mob/mom(5) pat/fat, apt/aft (AmE), harp (BrE)/half7. (1) The stresses are placed on the second syllable except for “promise”. We mayeasily conclude that the verbs usually are stressed on the second syllable. (2) Syllable representations of the words:collide [k2#laid] elect [i#lekt] consider [k2n#sid2]Chapter 3Morphology1. Define the following terms briefly.(1) morphology: the study of the structure of words.(2) morpheme: the smallest unit of language that carries meaning or serves a grammatical function.(3) free morpheme: a morpheme that can stand alone as a word.(4) bound morpheme: a morpheme that can not stand alone as a word, e.g.-ment (as in establishment), and -er (as in painter).(5) morph: the smallest meaningful phonetic segments of an utterance on thelevel of parole.(6) allomorph: a phonetic form in which a morpheme is realized, e.g. -s, -es, and -en are all allomorphs (in writing) of the plural morpheme.(7) derivation: the formation of new words by adding affixes to other words or morphemes in morphology and word formation.(8) clipping: the process by which parts of a word of more than one syllable have been cut off, and reduced to a shorter form.(9) acronym: words which are composed of the first letter of a series of words and are pronounced as single words. Examples: NATO, radar and yuppy.(10) initialism: Some new words are composed of the first letters of a series of words and pronounced by saying each letter in them. Such words are called initialism.(11) blending: A single new word can be formed by combining two separateforms. Typically, blending is finished by taking only the beginning of oneword and joining it to the end of another word. For example, brunch isformed by the shortened forms of breakfast and lunch.(12) root: the morpheme that remains when all affixes are stripped from a complex word, e.g. system from un- + system + atic + ally.(13) stem: the base towhich one or more affixes are attached to create a morecomplex form that may be another stem or a word. For example, book is thestem of bookish.(14) prefix: Affixes can be joined to the beginning of the root or stem, in which case they are called prefixes.(15) suffix: Affixes can be joined to the end of the root or stem, in which case they are called suffixes.2. (3), (5), (7)3. (1) simple: fly tree suite(2) bound morpheme rootfly / fly reuse re-use spiteful -ful spitepreplan pre-plan desks -s desk triumphed -ed triumphsuite / suite optionality -ality option untie un-tiedelight de-light fastest -est fast prettier -ier prettytree / tree justly -ly just deform de-formmistreat mis-treat dislike dis-like payment -ment paydisobey dis-obey premature pre-mature4. (1) Column I: ablaut (vowel modification)Column II: suppletionColumn III: stress modification(2) The process in the Column I is finished by changing the vowel of each word, while in Column II, the process is finished by changing vowel and consonantof each word.(3) Column I: awake/awoke bear/bore arise/aroseblow/blew bite/bit hide/hidlie/lay know/knew foot/feetgoose/geese tooth/teeth louse/liceColumn II: bad/worse are/were many/moreColumn III: #combine/com#bine #compress/com#press#conduct/con#duct #insert/in#sert#insult/in#sult #intern/in#tern5. (1) Omitted.(2) Other examples:#rerun (n.) – re#run (v.) #contrast (n.) – con#trast (v.)#convert (n.) – con#vert (v.) #desert (n.) – de#sert (v.)#export (n.) – ex#port (v.) #increase (n.) – in#crease (v.)#conduct (n.) – con#duct (v.) #object (n.) – ob#ject (v.)#content (n.) – con#tent (v.) #protest (n.) – pro#test (v.)#insult (n.) – in#sult (v.) #produce (n.) – pro#duce (v.)When a word belongs to different word classes, the stress of the word will be sometimes placed on different syllables. When all the words above are stressed on the first syllables, they are nouns, but if they have the second syllables stressed, the words become verbs.6. (1) It means “the inhabitant of ”.(2) It means “the person who does”.(3) The morphological rule working here is “n. + -er –– n.”, and the last phoneme of the noun, which the suffix -er is added to, should be a consonant.(4) The rule in (3) doesn’t work in the word discoverer because the last phoneme of discoverer is a vowel /2/.7. (1) inflection (2) derivation (3) inflection (4) inflection (5) derivation Chapter 4Syntax1. Define the following terms briefly.(1) syntax: the term used to refer to the structure of sentences and to the study of sentence structure.(2) word class: a group of words which are similar in function; words which aregrouped into word classes according to how they combine with other words,how they change their forms, etc.(3) prescriptive approach: This view regards grammar as a set of rules for the “proper” use of a language, that’s to say, it tries to lay down rules to tell peoplehow to use a language.(4) descriptive approach: the approach of linguistic studies, with which linguists collect samples of the language they are interested in and attempt to describe the regular structures of the language as they are used, not according to some view of how they should be used.(5) IC analysis: the approach to divide the sentence up into its immediate constituents by using binary cutting until obtaining its ultimate constituents. For example, the immediate constituents of “The man bought a car” are theman and bought a car. The immediate constituents of the man are the andman, and so on until no further cuts can be made. The ultimate constituentsof “The man bought a car” at the word level are the, man, bought, a, and car.(6) structural analysis: a type of descriptive approach to study the distribution of linguistic forms in a language through such methods as the use of “test frames”.(7) immediate constituent: Linguistic units can be divided into small constituents, which can be further analyzed into smaller constituents. This processcontinues until no further divisions are possible. The first division or units are known as immediate constituents.(8) ultimate constituent: Linguistic units can be divided into small constituents, which can be further analyzed into smaller constituents. This process continues until no further divisions are possible. The final division or units areknown as ultimate constituents.(9) constituent structural grammar: It refers to a grammar which analyzes sentences using only the idea of constituency, which reveals a hierarchy of structural levels.(10) transformational grammar: a type of grammar which attempts to define and describe by a set of rules or principles all the grammatical sentences (without ungrammatical ones) of a language.(11) ideational function: the use of language as a means of giving structure to our experience of the real or imaginary world.(12) interpersonal function: the use of language for maintaining social roles and interacting with others.(13) textual function: to create written or spoken texts which cohere within themselvesand which fit the particular situation in which they are used.2. Yes. As we know, morphology is the study of the internal structure, forms and classes of words, while syntax focuses on the structure and ordering of components within a sentence. The major distinction between morphology and syntaxis that the former is concerned with the internal composition of a word, while the latter is concerned with the combination of words.3. (2) Instead of using the form “suggest somebody to do something”, we usually use “suggest + that-clause” or “suggest doing”, here we’d better substitute “advise” for “suggest”(4) The word “request” is a transitive verb which should take an object directly, so the word “for” should be omitted.(6) The word “donate” cannot be followed by double objects as “donate somebody something”. Instead we always use “donate something to somebody”.(10) The subject of the verb “write” is usually a human; an “article” cannot write itself. In this case the passive construction is normally used: The article was very well writen.(11) Usually we don’t use “be bored of something/somebody”, but “be bored with something/somebody” which means losing interest in somebody/something.(13) Here “myself ” is a reflexive pronoun, which can’t be used as subject, and it should be replaced by “I”.(14) The word “surprise” is usually used as a transitive verb, so the expression “…surprise for you” is ungrammatical, and it can be replaced by “surprise somebody (with something)” or “I was surprised by your getting married.”(15) The word “sleep” is usually used as an intransitive verb, which can’t take an object. The cases of “sleep” being used as a transitive verb are semantically limited, as in “to sleep a good sleep” or “the room can sleep 3 people”.4. It’s ungrammatical, because “us” is the objective case which can’t serve as the subject,while “she” is the subjective case which can’t serve as the object. The sentence should be “We visit her on Sundays”. The personal pronouns “you” and “it” have the same form whether used as the subject or object.5. (1) NP: A Guns “N” Roses concert, an arena, some 2500 fans, a full-fledged riot,A Guns “N” Roses concert at an arena , A Guns “N” Roses concert at an arena near ST. Louis ,The trouble, venue security, a camera, the front, the stage, the front of the stage. PP: at an arena, at an arena near ST. Louis, near ST. Louis, in disaster, near the front, of the stage, near the front of the stage. VP: stageda full-fledged riot, asked venue security, confiscate a camera.(2) N: Guns, Roses, concert, arena, ST. Louis, disaster, fans, riot, trouble, Axl Rose, venue, security, camera, front, stage. Prep: at, near, in, of. V: end, stage, start, ask, confiscate, see.6. (1) You mustn’t end a sentence with a preposition.You mustn’t split infinitives.7. (i)SNP VP AdvArt N V NP Prep NPArt N Art NThe dog bit the man in the car.(ii)S ,Art N ,Art N ,Prep NP ,NP VP, Art N V NP P. The dog bit the man in the car.8. (1)a. Terry loves his wife and I love his wife, too.b. I love my wife as well as Terry loves his wife.(2) a. It’s yesterday that they said she would go.b. She would go yesterday as they said.(3) a. The governor is a street fighter who is dirty.b. The governor is a fighter in a dirty street.(4) a. The design has squares and circles, both of which are big.b. The design has big squares, and it also has some circles. (The sizes of the circles are not mentioned.)Chapter 5Semantics1. Define the following terms briefly.(1) semantics: the study of linguistic meaning.(2) truth-conditional semantics: an approach that knowing the meaning of the sentence is the same as knowing the conditions under which the sentence istrue or false, and knowing the meaning of a word or expression is knowingthe part that it plays in the truth or falsehood of the sentence containing it.(3) naming theory: the view that the meaning of an expression is what it refers to, or names.(4) behaviorist theory: the view that the meaning of a linguistic form is defined as observable behaviors which is an approach drawing on psychology.(5) use theory: the semantic theory according to which the meaning of an expression is determined by its use in communication and more generally, insocial interaction.(6) sense: the inherent part of an expression’s meaning, together with the context, determines its referent. For example, knowing the sense of a nounphrase such as the president of the United States in 2004 allows one to determine that George W. Bush is the referent.(7) reference: (in semantics) the relationship between words and the things, actions, events and qualities they stand for. An example in English is the relationshipbetween the word tree and the object “tree” (referent) in the realworld.(8) conceptual meaning: It means the meaning of words may be discussed interms of what they denote or refer to, also called denotative or cognitive meaning. It is the essential and inextricable part of what language is and is widely regarded as the central factor in verbal communication. For instance, the conceptual meaning of “he” in English is any male person or male animal.(9) connotative meaning: It is the communicative meaning that a word or a combination of words has by virtue of what it refers to, over its purely conceptual meaning. For example, the connotative meaning of “woman” is emotional,frail, inconstant, irrational, etc.(10) semantic field: the organization of related words and expressions into asystem which shows their relationship to one another. For example, kinship terms such as father, mother, brother, sister, uncle, aunt belong to a semantic field whose relevant features include generation, sex, membership of the father’s or mother’s side of family.(11) lexical gap: the absence of a word in a particular place in a semantic field of a language. For instance, in English we have brother versus sister, son versus daughter, but no separate lexemes for “male” and “female” cousin.(12) componential analysis: (in semantics) an approach to the study of meaning which analyzes a word into a set of meaning components or semantic features.For example, the meaning of the English word boy may be shown as[+human][+male][-adult].(13) semantic feature: the smallest units of meaning in a word. The meaningof word may be described as a combination of semantic components orfeatures. For example, the feature [+male] is part of the meaning of father,and so is the feature [+adult], but other features are needed to make up the whole meaning of father. Often, semantic features are established by contrast and can be stated in terms of [+] and [-], e.g. woman has the semantic features [+human], [-male] and [+adult].(14) synonym: the sense relations of equivalence of meaning between lexical items, e.g. small/little and dead/deceased.(15) antonym: the sense relation of various kinds of opposing meaning between lexical items, e.g. big/small, alive/dead and good/bad.(16) hyponymy: the sense relation between terms in a hierarchy, where a more particular term (the hyponym) is included in the more general one (the superordinate): X is a Y, e.g. a beech is a tree, a tree is a plant.(17) meronym: the sense relation between body and its parts which are not only sections of the body but defined in terms of specific functions. For example, the head is the part of the body which carries the most important sense organs,i.e. eyes, ears, nose and tongue.(18) semantic role: the way in which the referent of a noun phrase is involved in the situation described or represented by the clause, for example as agent, patient, or cause.(19) entailment: the relationship between two sentences where the truth of one (the second) is inferred from the truth of the other, e.g. Corday assassinated Marat and Marat is dead; if the first is true, the second must be true.(20) presupposition: implicit assumptions about the world required to make an utterance meaningful or appropriate, e.g. “some tea has already been taken”is a presupposition of “Take some more tea!”2. (1) He waited by the bank.a. He waited by the financial institution which people can keep their moneyin or borrow from.b. He waited by the bank of the river.(2) Is he really that kind?a. Is he really that type of person?b. Is he really that kind-hearted?(3) We bought her dog biscuits.a. We bought dog biscuits for her.b. We bought biscuits for her dog.(4) He saw that gasoline can explode.a. He saw that gasoline container explode.b. He saw that gasoline may explode.(5) Fifty soldiers shot three wild foxes.a. Fifty soldiers shot three wild foxes in total.b. Each of the fifty soldiers shot three wild foxes.(6) He saw her drawing pencils.a. He saw her pencils for drawing.b. He saw her drawing the picture of pencils.3. (2) (4) (5) (8) are antonyms; (1) (3) (6) (7) are synonyms.4. charity: kindness, sympathy, church, helpfuliron: strong, brave, hard, determinedmole: traitor, betrayal, spysnow: pure, virgin, cleanstreet: homeless, living hard, pitiable5. (1) a. hoard b. scribble c. barn, method d. olfactory(2) a. acquire b. tell c. way d. smell(3) a. buy, win, steal. b. talk, tell c. road, way, path d. smellThese words are less marked in their sets because they are more usual andtend to be used more frequently. They consist of only one morpheme andare easier to learn and remember than others. They are also often broader in meaning and cannot be described by using the name of another member ofthe same field.6. homophones: sea-see, break-brake; polysemies: sea, break, prayer, mature, trace, househomonyms: ear.7. In a semantic field, not all lexical items necessarily have the same status. The less marked members of the same semantic field (1) are usually easier to learn and remember than more marked members; (2) consist of only one morpheme incontrast to more marked members; (3) cannot be described by using the name of another member of the same field; (4) tend to be used more frequently than more marked terms; (5) broader in meaning than more marked members; (6) are notthe result of the metaphorical usage of the name of another object or concept, but more marked are.8. (1) a. bachelor, man, son, paperboy, pope, chiefb. bull, rooster, drake, ram.The (a) and (b) words are male.The (a) words are human.The (b) words are animals.(2) a. ask, tell, say, talk, converseb. shout, whisper, mutter, drawl, hollerThe (a) and (b) words are realized by sounds.The (a) words are normal voice quality.The (b) words are produced by modifying one’s normal voice quality.(3) a. walk, run, skip, jump, hop, swimb. fly, skate, ski, ride, cycle, canoe, hang-glideThe (a) and (b) words are sports (movement).The (a) words are sports without instruments.The (b) words are sports with instruments.Chapter 6Pragmatics1. Define the following terms briefly.(1) pragmatics: a branch of linguistics that studies language in use.(2) deixis: the marking of the orientation or position of entities and situations with respect to certain points of reference such as the place (here/there) and time (now/then) of utterance.(3) reference: (in semantics) the relationship between words and the things, actions, events, and qualities they stand for.(4) anaphora: a process where a word or phrase (anaphor) refers back to another word or phrase which was used earlier in a text or conversation.(5) presupposition: implicit assumptions about the world required to make an utterance meaningful or appropriate, e.g. “some tea has already been taken”is a presupposition of “Take some more tea!”(6) Speech Act Theory: The theory was proposed by J. L. Austin and has been developed by J. R. Searle. Basically, they believe that language is not only used to inform or to describe things, it is often used to “do things”, to perform acts. In saying “Sorry”, you are performing an act of apology.(7) indirect speech act: an utterance whose literal meaning (location) and intended meaning (illocution) are different. For example, Can you pass thesalt? is literally a yes/no question but is usually uttered as a request or polite directive for action.(8) the Cooperative Principle: a principle proposed by the philosopher Paul Grice whereby those involved in communication assume that both partieswill normally seek to cooperate with each other to establish agreed meaning.It is composed of 4 maxims: quality, quantity, relation and manner.(9) the Politeness Principle: politeness is regarded by most interlocutors as a means or strategy which is used by a speaker to achieve various purposes,such as saving face, establishing and maintaining harmonious social relationsin conversation. This principle requires speakers to “minimize the expression of impolite beliefs”. It is composed of 6 maxims: Maxims of Tact, Generosity, Approbation, Modesty, Agreement and Sympathy.(10) conversational implicature: the use of conversational maxims in the Cooperative Principle to produce extra meaning during conversation.。
