English Lexicology(英语词汇学)
Lexicology(词汇学): is a branch of linguistics, inquiring into the origins and meanings of words.
The Nature and Scope of English lexicology：
English lexicology aims at investigating and studying the morphological structures of English words and word equivalents, their semantic structures, relations, historical development, formation and usages.
The subjects that English Lexicology correlated with and extent to：
English Lexicology is correlated with such linguistic disciplines as morphology( 形态学), semantics(语义学), etymology(词源学),stylistics (文体论) and lexicography(词典学) The reason for a student to study English lexicology：
According to the textbook, English Lexicology will definitely be beneficial for students of English.
A good knowledge of morphological structures of English words and rules of
word-formation will help learners develop their personal vocabulary and consciously increase their word power. The information of the historical development and the principles of classification will give them a deeper understanding of word-meaning and enable them to organize, classify and store words more effectively. The understanding and their sense relations will gradually raise their awareness of meaning and usage, and enable them use words more accurately and appropriately. A working knowledge of dictionaries will improve their skills of using reference books and raise their problem-solving ability and efficiency of individual study.
Chapter1--Basic concepts of words and vocabulary
Word(词的定义):A word is a minimal free form of a language that has a given sound and meaning and syntactic function. (1)a minimal free form of a language (2)a sound unity (3)a unit of meaning (4)a form that can function alone in a sentence
Sound and meaning(声音与意义): almost arbitrary,“no logical relationship between the sound which stands for a thing or an idea and the actual thing and idea itself”
Sound and form(读音和形式):不统一的四个原因( 1 )the English alphabet was adopted from the Romans,which does not have a separate letter to represent each other ( 2 ) the pronunciation has changed more rapidly than spelling over the years ( 3 ) some of the difference were creates by the early scribes (4) the borrowings is an important channel of enriching the English vocabulary
Vocabulary(词汇): all the words in a language make up its vocabulary
Classification of English Words：
By use frequency:basic word stock&nonbasic vocabulary
By notion:content words&functional words
By origin:native words&borrowed words
Thebasic word stock(基本词汇): is the foundation of the vocabulary accumulated over centuries and forms the common core of the language. Though it constitute a small percentage of the EV, it is the most important part of vocabulary.
The Fundamental Features of the Basic Word Stock(基本词汇的特征):
1)All-National character (全民通用性 most important ) 2)Stability (相对稳定性)
3)Productivity (多产性) 4)Polysemy (多义性) 5)Collocability (可搭配性)
没有上述特征的words:(1)Terminology(术语) (2)Jargon (行话) (3)slang (俚语) (4)Argot (暗语) ( 5 ) Dialectal words( 方言) (6) Archaisms (古语) (7) Neologisms (新词语) :Neologisms means newly-created words or expressions, or words that have taken on new meanings.(email)
Content words/notional words实词(cloud, run walk, never, five, frequently )and functional words/empty words虚词(on, of, and, be, but )
Native Words and Borrowed Words
Native words(本族语词): known as Anglo-Saxon words (50,000-60,000), are words brought to Britain in the 5th century by the Germanic tribes. (mainstream of the basic word-stocks).Two other features:(1)neutral in style (2)frequent in use
Borrowed words/Loan words(外来语词): words taken over from foreign languages.(80% of modern EV)
4Types of loan words:
1) denizens(同化词): (shirt from skyrta(ON))
2) aliens (非同化词/外来词 ) :are borrowed words which have retained their original pronunciation and spelling (kowtow (CH) 磕头)
3) translation loans(译借词):按其他语言方式组成英语 long time no see (from China)
4) semantic loans (借义词)： they are not borrowed with reference to the form,but their meanings are borrowed
Chapter2the development of the English Vocabulary
The Indo-European Language Family(印欧语系)
The Eight Groups in Indo-European Family of Languages (8 大印欧语群)
The Eastern set:
( 1 ) The Balto-slavic Group (波罗的-斯拉夫语族)： Russian,Bulgarian,Polish,Czech etc. ( 2 ) The Indo-Iranian Group (印度-伊朗语族)： Hindi,Bengali,Persian etc.
(3)The Armenian Group (亚美尼亚语族)： Armenian.
(4)The Albanian Group (阿尔巴尼亚语族)： Albanian.
The Western set:
(5)The Hellenic Group (古希腊语族)： Greek.
(6)The Italian Group (意大利语族)： Latin ,Romance languages(French,Italian,Spanish, portuguese,Romanian) etc.
(7)The Celtic Group (凯尔特语族)： Irish,Welsh,Breton etc.
(8)The Germanic Group (日耳曼语族)：
Flemish,German,Dutch,Scandinavian(Norweigian, Swedish,Danish,Icelandic) etc.
The Three Stages of Development of the English Vocabulary:
1 Old English (450-1100) (vocabulary 50,000 to 60,000):was I high inflected language.
2 Middle English (1150-1500):retaines much fewer inflections
3 Modern English (1500-up to now): in fact more than 25% of modern E words come almost directly from classical languages. In Modern E, words endings were mostly lost with just a few expections.English has evolved from a synthetic language(Old English) to the present analytic language.
Modes of Vocabulary Development(词汇的发展模式):
1)creation 创造新词： the formation of new words by using the existing materials,namely toots,affixes and other elements.( 最重要方式)
2)semantic change 旧词新义 :does not increase the number of word forms but create many more new useages of the words.
3) borrowing 借用外来词 :constitute merely 6 to 7 percent of all new words Reviving words or obsolete words also contributes to the growth of English vocabulary though quite insignificant.
Chapter 3 Word Formation I
Morpheme(词素):the smallest functioning unit in the composition of words
Allomorph(词素变体): is a different variant form of a morpheme ，differ in phonological and spelling form, but at the same in function and meaning
Type of Morpheme( 词素的分类)
( 1 )Free Morphemes(自由词素) : have complete meaning in themselves and can be used as free grammatical units in sentences. A free morpheme is one that can stand by itself. (independent).
( 2 ) Bound Morpheme(粘着语素): A bound morpheme is one that cannot stand by itself. Bound Morpheme includes two types: (1) bound root( 粘附词根) (2)Affix(词缀) Affixes can be put into two groups:
1)Inflectional affixes ( 屈折词缀):affixes attached to the end of words to indicate grammatical relationships are inflectional,thus known as inflectional morphemes.
2)Derivational affixes( 派生词缀): A) prefix: A prefix comes before words. B)suffix:An adjective suffix (形容词后缀) that is added to the stem, whatever class is belongs to , the result will be an adjective.
Free Morpheme =free root (自由词根)
Morpheme(词素)
Bound root
bound derivational

inflectional
Root and stem (词根和词干)
The differences between root and stem:
A root is the basic form of a word which cannot be further analyzed without total loss of identity.
A stem is the surplus part after the cutting of inflectional morpheme in a word with inflectional morphemes,can be further analyzed, it sometimes could be a root.
prefix
suffix
Chapter4Word-Formation II(构词法)
1.Affixation词缀法( Derivation 派生法)：the formation of words by adding word-formaing or derivational affixes to stem.
( 1 ) Prefixation(前缀法)：It's the formation of new words by adding a prefixes to stems.
1)Negative prefixes(否定前缀): un-,non-,in-,dis,a- ,il-,ir-,im-,etc.disobey(not obey)
2)Reversative prefixes (逆反前缀) : un-,de- ，dis- etc. unwrap(open)
3) Pejorative prefixes: mis (贬义前缀)： mis-， mal-, pseudo- etc.misconduct(bad behaviour)
4) Prefixes of degree or size( 程度前缀)：
arch-,extra-,hyper-,macro-,micro-,mini-,out-,over-,sub-,super-,sur-,ultra-,under-,ect. overweight
5) Prefixes of orientation and attitude (倾向态度前缀) :contra-,counter-,anti-,pro- etc.anti-nuclear
6)Locative prefixes (方位前缀) :extra-,fore-,inter-,intra-,tele-,trans-, etc. extraordinary(more than ordinary)
7) Prefixes of time and order(时间和顺序前缀) :fore-,pre-,post-,ex-,re- etc. monorail(one rail)
8) Number prefixes (数字前缀) :uni- ，mono-, bi- ，di-, tri-,multi- ，poly- ，semi-，etc.bilingual(concerning two languages)
9) Miscellaneous prefixes (混杂前缀)： auto-, neo-, pan-, vice-.vice-chairman(deputy chairman)
(2)Suffixation (后缀法) : It's the formation of a new word by adding suffixes to stems. 1)noun suffixes 2)adjective suffixes 3)Adverb suffixes 4)verb suffixes
https://www.wendangku.net/doc/0f19480070.html,pounding复合法(also called composition)
Compounding: is the formation of new words by joining two or more stems
Compounds are written in three ways: solid 连写(airmail) ，hyphenated 带连字符
(air-conditioning)and open 分开写(air force, air raid) Formation of compounds (复合词的形式)
( 1 ) noun compounds ：e.g. : air + plane = airplane,flower + pot = flower pot
( 2 ) adjective compounds ： e.g. acid + head = acid-head
( 3 ) verb compounds ： e.g. house + keep = housekeep
3.Conversion转类法
Conversion: is the formation of new words by converting words of one class to another class. (功能转换，又叫零派生 .functional shift/zero-derivation )
4.Blending拼缀法
Blending : is the formation of new words by combining parts of two words or a word plus a part of another word. e.g: motor + hotel = motel, smoke + fog = smog, formula + translation = FORTRAN
5.Clipping截短法
Clipping:is to shorten a longer word by cutting a part off the original and using what remains instead.e.g. plane from airplane, phone from telephone. 四种形式：
1).Front clippings 删节前面 (phone from telephone)
2).Back clippings 删节后面 (dorm from dormitory)
3).Front and back clippings 前后删节(flu from influenza)
4).Phrase clippings 短语删节(pop from popular music)
6.Acronymy首字母缩写法
Acronymy:is the process of forming new words by joining the initial letters of names of social and political organizations or special noun phrases and technical terms.
( 1 ) Initialism (首字母缩写词法) : initialisms are words pronounced letter by letter. e.g.: BBC(for British Broadcasting corporation)
( 2 ) Acronym (首字母拼音法) :Acronyms are words formed from initial letters but pronounced as a normal word. E.g. :TEFL(teaching English as a foreign language)
7.Back-formation(逆生法，逆构词)
Back-formation is considered to be the opposi te process of suffixation. It’s the method of creating words by removing the supposed suffixes. (greed from greedy)
8.Words From Proper Name(专有名词转成法):
Names of people, places, book, and tradenames (e.g. : sir watt siemens( 人名) -- watt (瓦特，电功率单位)
Chapter5Word Meaning
The meanings of“Meaning”(“意义”的意义)
Reference(所指):It is the relationship between language and the word. It is the arbitrary and conventional. It is a kind of abstraction, yet with the help of context, it can refer to something specific.
Concept(概念) :which is beyond language, is the result of human cognition( 认
识),reflecting the objective world in the human mind.
Sense(意义) :It denotes the relationship inside the language.‘The sense of an expression is its place in a system of semantic relationshi ps with other expressions in the language.’
Motivation(理据)：It accounts for the connection between the linguistic symbol and its meaning.
1) Onomatopoeic motivation (拟声理据) :words whose sounds suggest their meaning, for these words were creates by imitating the natural sounds or noises. Knowing the sounds of the words means understanding the meaning. E.g. : bang, ping-pong, ha ha.
2)Morphological motivation (形态理据):multi-morphemic words and the meaning of many are the sum total of the morphemes combines. E.g.: airmail, miniskirt .例外： black market, ect.
3)Semantic motivation (词义理据)： refers to the mental associations suggested by the conceptual meaning of a word. It explains the connection between the literal sense and figurative sense of the word. E.g:the foot of the mountain(foot)
4)Etymological motivation (词源理据):the history of the word explains the meaning of the word. E.g:pen-feather
Types of meaning(词义的类别)
1.Grammatical Meaning (语法意义) :indicates the grammatical concept or relationships (becomes important only in actual context)
2.Lexical Meaning (词汇意义)
(Lexical meaning and grammatical meaning make up the word-meaning)
Lexical meaning has 2 components 内容: Conceptual meaning( 概念意义) and associative meaning(关联意义)
1 ) Conceptual meaning( 概念意义): also known as denotative meaning( 外延意义) is the meaning given in the dictionary and forms the core of word-meaning.
2 ) Associative meaning( 关联意义):is the secondary meaning supplemented to the conceptual meaning.
[4types:
( 1 ) Connotative ( 内涵意义 ) ： the overtones or associations suggested by the conceptual meaning, traditionally known as connotations.( 例如“母亲”经常与“爱”“关心”“温柔”联系起来)
( 2 ) Stylistic ( 文体意义 ) ： many words have stylistic features, which make them appropriate for different contexts.
( 3 ) Affective(感情意义) ：indicates the speaker’s attitude towards the person or thing in question.这种情感价值观分两类：褒义和贬义 appreciative & pejorative
( 4 ) Collocative (搭配意义)： is the part of the word-meaning suggested by the words
before or after the word in discussion.]
Chapter6--Sense relation and semantic field(语义关系和语义场)
Polysemy(多义关系)
Two approached to polysemy (多义关系的两种研究方法) :
1.diachronic approach( 历时方法) ：from the diachronic point of view, polysemy is assumed to be the result of growth and development of the semantic structure of one and same word. First meaning is the primary meaning , the later meanings are called derived meanings.
2. synchronic approach (共时方法) : synchronically, polysemy is viewed as the coexistence of various meanings of the same word in a certain historical period of time. 基本意义是central meaning , 次要意义是 derived meaning.
Two processes of development (词义的两种发展类型) :
1. radiation (辐射型) ：is a semantic process in which the primary meaning stands at the
centre and the secondary meanings proceed out of it in every direction like rayes. (e.g: face, neck)
2. concatenation (连锁型) :is the semantic process in which the meaning of a word move
gradually away from its first sense by successive shifts until there is not a sign of connection between the sense that is finally developed and that which the term had at the beginning.(e.g:treacle)
3. In radiation, each of the derived meaning is directly connected to the primary meaning.
In concatenation, each of the later meaning is related only to the preceding one like chains. Though the latest sense can be traced back to the original, there is no direct connection in between.
4. They are closely related, being different stages of the development leading to
polysemy. Generally, radiation precedes concatenation. In many cases, the two processes work together, complementing each other.
Homonymy(同形同音异义关系) :words different in meaning but either identical both in sound and spelling or identical only in sound or spelling.
Types of homonyms(同音同形异义关系的类别)
1 )Perfect homonyms(完全同音同形异义词) ：words identical both in sound and spelling, but different in meaning.
2)Homographs (同形异义词) :words identical only in spelling, but different in sound and meaning.(最多最常见)
3 ) Homophones (同音异义词) ：words identical only in sound but different in spelling and meaning.
Origins of homonyms(同形同音异义词的来源)
1 ) change in sound and spelling ：(eare-ear, lang-long, langian-long)
2 ) borrowing (feria-fair, beallu-ball, baller-ball )
3 ) Shortening(缩略): (ad-advertisement,)
The differentiation of Homonyms from Polysemes (同音同形异义词和多义词的区别 )：1)The fundamental difference : Homonymy refers to different words which happen to share the same form and polysemy are the one and same word which has several distinguishable meanings.
2)One important criterion is to see their etymology( 词源)：Homonymys are from different sources. Polysemant is from the same source.
3)The second principle consideration is semantic relatedness( 语义关联): The various meanings of polysemant are correlated and connected to one central meaning. Meanings of different homonymys have nothing to do with one another. In dictionaries, a polysemant has its meaning all listed under one headword whereas homonyms are listed as separate entries.
Rhetoric features of homonyms( 同形同音异义词的修辞特色)：As homonyms are identical in sound or spelling, particularly homophones, they are often employed to create puns for desired effect of, say, humor, sarcasm or ridicule.
Synonymy(同义关系): one of two or more words in the English language which have the same or very nearly the same essential meaning .
Types of Synonymy(同义词的类别) :
(1) Absolute synonyms(完全同义词) ：also known as complete synonyms are words which
are identical in meaning in all aspects, i.e. both in grammatical meaning and lexical meaning, including conceptual and associative meanings.[ Absolute synonyms are restricted to highly specialized vocabulary in lexicology. ]
(2) relative synonyms (相对同义词) :also called near-synonyms are similar or nearly the
same in denotation, but embrace different shades of meaning or different degrees of a given quality.(e.g: change/alter/vary, stagger/reel/totter, strange/odd/queer, idle/lazy/indolent)
Sources of synonyms(同义词的来源) :
1)Borrowing (借词)：最重要的来源(room-chamber, foe-enemy, help-aid, leave-depart, wise-sage, buy-purchase)
2)Dialects and regional English (方言和地区英语)
3)Figurative and euphemistic use of words (单词的修饰和委婉用
法) :occupation/profession-walk of life, dreamer--star-gazer, drunk-elevated, lie-distort of fact.
4)Coincidence with idiomatic expressions (与习惯表达一致) :win-gain the upper hand, decide-make up one’s mind, finish -get through, hesitate-be in two minds, help-lend one a hand.
Discrimination of Synonyms
(1) difference in denotation 外延不同. Synonyms may differ in the range and intensity of
meaning.(rich-wealthy, work-toil, want-wish-desire)
(2) difference in connotation 内涵不同. By connotation we mean the stylistic and emotive
colouring of words. Some words share the same denotation but differ in their stylistic appropriateness. ( 借词：answer-respond, storm-tempest, wood-forest, handy-manual, unlike-dissimilar, homely-domestic, fleshy-carnal. 中性词：policeman-constable-bobby-cop, ask-beg-request. 古语词、诗歌：ire/anger,
bliss-happiness, forlorn-distresses, dire-dreadful, list-listen, enow-enough, save-expect, mere-lake )
(3) difference in application. Many words are synonymous in meaning but difference in
usage in simple terms. They form different collocations and fit into difference sentence patterns. (allow sb. to do sth.- let sb. do sth. / answer the letter-reply to the letter)
Antonymy(反义关系) :it is concerned with semantic opposition. Antonyms can be defined as words which are opposite in meaning.
Types of Antonyms:
1)contradictory terms ( 矛盾反义词): these antonyms truly represent oppositeness of meaning. 特点：①The assertion of one is the denial of the other. ②Such antonyms are non-gradable. They cannot be used in comparative degrees and do not allow adverbs of intensity like “very” to qualify them . (e.g: single/married)
2)contrary terms (对立反义词) : antonyms of this type are best viewed in terms of a scale running between two poles or extremes.(e.g: old/young, rich/young, big/small) The two opposites are gradable and one exists in comparison with the other.
3)relative terms (关系反义词)：this type consists of relational opposites. ( parent/child, husband/wife, employee/employer, sell/buy, receive-give )
Some of the characteristics of antonyms(反义关系的特点):
1)antonyms are classified on the basis of semantic opposition( 语义对立)
2)a word which has more than one meaning can have more than one antonym
3)antonyms differ in semantic inclusion (语义内涵 )
4)contrary terms are gradable antonyms ，differing in degree of intensity, so each has its own corresponding opposite.(hot/warm: hot-cold/warm-cool)
The use of antonyms(反义词的使用)
1 ) Antonyms are helpful and valuable in defining the meaning of words.
2)To express economically the opposite of a particular thought for the sake of contrast.(e.g :now or never, rain or shine, friend or foe 敌友，weal and woe 哀乐)
3 ) To form antithesis(对比法) to achieve emphasis by putting contrasting idea together. (proverbs and sayings: easy come , easy go./ more haste, less speed.)
Hyponymy(上下义关系): Hyponymy deals with the relationship of semantic inclusion. The meaning of a more specific word is included in that of another more general word. For example, a cat is hyponym of animal
Superordinate and Subordinate(上义词和下义词)：use subordinates which are concrete and precise ,presenting a vivid verbal picture before the reader. Superordinates which convey only a general and vague idea.
Semantic Field(语义场)
Viewing the total meaning in this way is the basis of field theory.
e.g.(apple, pear, peach, date, mango, orange, lemon, etc. make up the semantic field of ‘fruits’)
The semantic field of the same concept may not have the same members in different language.
e.g.(aunt in English, may means “父亲的姐姐，妈妈的姐姐，父亲哥哥的妻子” in Chinese.(122)
Chapter7Changes in Word Meaning词义的演变
Vocabulary is the most unstable element of a language as it is undergoing constant changes both in form and content. Comparatively the content is even more unstable than the form.
Types of Changes(词义变化的种类)
1.Extension/generalization(词义的扩大): is the name given to the widening of meaning which some words undergo. It is a process by which originally had a specialized meaning has now become generalized.(e.g: manuscript, fabulous, picture, mill, journal, bonfire, butcher, companion)
2.Narrowing/specialization(词义的缩小)：is the opposite of widening meaning. It is
a process by which a word of wide meaning acquires a narrower or specialized sense. In
other words, a word which used to have a more general sense becomes restricted in its application and conveys a special meaning in present-day English.(e.g: deer, corn, garage, liquor, meat, disease, poison, wife, accident, girl). [ when a common word is turned into a proper noun, the meaning is narrowed accordingly. ]
3.Elevation/amelioration(词义的升华):refers to the process by which words rise from humble(粗陋的) beginnings to positions of importance. [nice, marshal, constable, angel, knight, earl, governor, fond, minister, chamberlain ]
4.Degradation/pejoration(词义的降格):A process whereby words of good origin fall into ill reputation or non-affective words come to used in derogatory(贬损的) sense.[boor, churl, wench, hussy, villain, silly, knave, lewd, criticize, lust ]
5.Transfer(词义的转移): Words which were used to designate 指明one thing but later changed to mean something else have experienced the process of semantic transfer.
Causes of Semantic Change(词义变化的原因)
1.Extra-linguistic factors(词义演变的语言外部因素):
1) Historical reason( 历史原因)：Increased scientific knowledge and discovery, objects, institutions, ideas change in the course of time. E.g: pen, car, computer.
2 )Class reason(阶级原因)：The attitude of classes have also made inroads into lexical meaning in the case of elevation or degradation.
3) Psychological reason( 心理原因)：the associated transfer of meaning and euphemistic use of words are often due to psychological factors. Such slow, humble and despised occupations take more appealing names is all due to psychological reasons.
2.Linguistic factors(语言内部原因) ：the change of meaning may be caused by internal factors with in the language system.
1)shorting 缩略:gold-gold medal, gas-coal gas, bulb-light bulb, private-private soldier
2)borrowing 借用:deer-animal-beast
3)analogy 类推:
Chapter8Meaning and Context词义和语境
Context in its traditional sense refers to the lexical items that precede or follow a given word. Modern linguists have broadened its scope to include both linguistic and
extra-linguistic contexts.
Two types of context(语境的种类)
1.Extra-linguistic context/Non-linguistic situation(非语言语境)：In a broad sense, context includes the physical situation as well, which embraces the people, time, place, and even the whole cultural background. (look out, weekend, landlord )
2.Linguistic context/grammatical context(语言语境)：In a narrow sense, it refers to the words, clauses, sentences in which a word appears. It may cover a paragraph, a whole chapter and even the entire book. 分为两类：
1) Lexical context(词汇语境) ：It refers to the word that occurs together with the word in question. (e.g: paper, do)
2) Grammatical context (语法语境)：It refers the situation when the meaning of a word may be influenced by the structure in which it occurs. (e.g: become)
The role of context(语境的作用)
1.Elimination of ambiguity(消除歧义)
1 ) Ambiguity due to polysemy or homonymy.
2 ) Grammatical structure can also lead to ambiguity
如何消除歧义？——①extend the original sentence ②alter the context a little
2.Indication of referents(限定所指)
如何限定所指？——①with clear context ②with adequate verbal context
3.Provision of clues for inferring word-meaning(提供线索以猜测词义)
1)definition
2)explanation
3)example
4)synonymy
5)antonymy
6)hyponymy (上下义关系)
7)relevant details
8)word structure
Chapter9English Idioms英语习语
Idioms(习语的定义) : are expressions that are not readily understandable from their literal meaning of individual elements. In a broad sense, idiom may include colloquialisms (俗语) , Catchphrases (标语) ,slang expressions (俚语) ,proverbs (谚语) ,etc. They form an important part of the English vocabulary.
Characteristics of Idioms(英语习语的特点)
1.Semantic unity(语意的整体性)：words in the idiom they have lost their individual identity. Their meanings are not often recognizable in the meaning of the whole idiom.
The semantic unity of idioms is also reflected in the illogical relationship between the literal meaning of each of the idiom.
2.Structural stability(结构的稳定性):thestructureof an idiom is to a largeextent
un changeable.
1) the constituents of idioms cannot be replaced
2) the word order cannot be inverted or changed
3) the constituents of idioms cannot be deleted or added to, not even an article.
4) many idioms are grammatically unchangeable

英语词汇学第一章
Chapter 1 1.1 What Is a Word 词的概念：A word can be defined as a meaningful group of letters. （一个词可以被定义为一组有意义的字母） 词包含以下几点： ① a minimal free form of a language.一门语言中最小的形式 ② a sound unity.一个声音统一体 ③ a unit of meaning.一个意义单位 ④ a form that can function alone in a sentence.能在句子中起独立作用的一个形式 A word is a free form of a language that has a given sound and meaning and syntactic function.词是一门语言中具有一定的声音，意义和句法功能的最小形式 Words can be simple and complex.词可以是简单的也可以是复杂的 1.2 Sound and Meaning 声音与意义之间的关系：This symbolic connection is almost always arbitrary,and there is no logical relationship between the sound and the actual thing and idea itself .The relationship between them is conventional. 这种象征性的联系几乎总是任意的，声音与实际的事物和观念本身没有逻辑关系。他们之间的关系是约定俗成的。 1.3 Sound and Form 读音与拼写不一致的原因：①The English alphabet was adopted from the Romans,which does not have a separate letter to represent each sound in the language. ②The pronunciation has changed more rapidly than spelling over the years. ③Some of the differences were created by the early scribes. ①英语字母表是从罗马人那里采用的，罗马人没有一个单独的字母来代表语言中的每个 声音。 ②这些年来，发音的变化比拼写的变化更快。 ③有些差异是由早期的抄写员造成的。

大家请注意：笔记中大多数是以名词解释的形式出现的，这些是绝对的基础，应该一字不漏的背下来。其实不少简答题也就是几个定义的汇总，再加上个例子就可以拿满分了。区分两个词的区别，主要还是指明其各自的定义。 第一章Basic Concepts of Words and Vocabulary 1. 词的定义Word —— A word is a minimal free form of a language that has a given sound and meaning and syntactic function. 2.声音与意义的关系There is no logical relationship between sound and meaning as the symbolic connection between them is arbitrary and conventional. E.g. “woman” means ’Frau’ in German，’Femme’ in French and ’Funv ’in Chinese. On the other hand，the same sound /rait/ can mean right，rite and write，though denoting different things，yet have the same sound. 3.读音与拼写不一致的原因The difference between sound and form result from 4 major factors. （At least 80%of the English words fit consistent spelling patterns） a）. the internal reason is English alphabet does not have a separate letter to represent each sound in the language. b）. Pronunciation has changed more rapidly than spelling c）. Influence of the work of scribes/printing freezes the spelling of words in 1500 d）. Borrowing of foreign language 4. 词汇的含义Vocabulary —— Vocabulary is most commonly used to refer to the sum total of all the words of a language. It can also refer to all the words of a given dialect，a given book，a given displine and all the words possessed by an individual person as well as all the words current in a particular period of time in history. The general estimate of the present day English vocabulary is over 1 million words. 5.词汇的分类的原则Classification of Words—by use frequency，by notion，by origin the English vocabulary consist of words of all kinds. they can be classified by different criteria and for different purpose . words may fall into the word stock and nonbasic vocabulary by use frequency, into content words and functional words by notion , and into native words and borrowed words by origin. 基本词汇的特点 1）. Basic word stock – the foundation of the vocabulary. 1.all national character （most important）– natural phenomena most common things and phenomena of the human body and relations world around us names of plants and animals action，size，domain，state numerals，pronouns，prep. ，conj.

The morpheme is to the morph what a phoneme is to a phone: 语素是一个音素发音的形素 ①single morphs单一语素词： bird, tree, green, sad, want, desire, Most morphemes are realized by single morphs,Words of this kind are called monomorphemic words.大多数语素通过单个的形素实现，语素与词相同叫做单一语素词. These morphemes coincide withe words as they can stand by themselves and function freely in a sentence.Words of this kind are called monomorphemic words. 这些语素与词相同，由于它们能代表含义而且能够在句子中自由起作用。这种词叫做单一语素词 ②The plural morpheme复数语素： {-s} /s / after the sounds/t, p, k/ packs, cheats, shapes /-z/ after /d, b, g, l/ beds, bottles, fads /iz/ after/s, z, ?, ?, t?, d?/classes, dishes, garages, damages Some morphemes, however, are realized by more than one morph according to their position in a word. Such alternative morphs are known as allomorphs. 一些语素被按照形素在其中排列而认识，那些替换的形素被称为”语素变体”。 Allomorphs as such do not occur at random, but are phonetically conditioned and thus predictable.语素变体不是随机发生的，是语音条件下可以预测的 ③zero morph零形素：deer -deer, fish-fish （There are cases where the allomorphs of the plural morpheme are unusual. It can be realized by the change of an internal vowel 某种情况是复数词素的变体不常见。他可以通过内部元音的变化来认知） ④the past tense过去式 {-ed}：1）/t/ after a verb ending with /p, k/ worked, helped 2）/d/ after vowels and sounds like /m, n, ?, l/ tried, warmed, lived , enabled 3）/id/ after /t, d/ wanted, landed affixational morphemes附加语素 This prefix : depending on the first sound of the stem to which the prefix is added.
