Chapter 1Word-Structure1. The definition of morpheme1.1 What is the smallest meaningful linguistic unit of language?- morphemeWhat are words composed of? - Words are formed by morphemes. A word is the smallest unit that stands alone to communicate meaning.1.2 What are the Chinese equivalents对应词of morpheme? 语素词素-形位2.1 Morphemes may be classified into free and bound.Free morphemes, also called content morphemes, may constitute words by themselves. These morphemes have complete meanings in themselves and can be used as free grammatical units in sentences. So we may say that free morphemes are free roots.Bound morphemes = Bound root + affixes, known as grammatical morphemes, must appear with at least one other morpheme, either free or bound. Bound morphemes are chiefly found in derived words, e.g. recollection, idealistic, ex-prisoner2.2 Morphemes may also be classified into roots (or root morphemes) and affixes (or affixational morphemes).Task:(1) Read the following words and find the root in each word.heart, hearten, dishearten, heartless, hearty, heartiness,sweetheart, heartbroken, kind-hearted, whole-heartedly.(2) What is your definition of root?A root is the part of the word-form which remains when all the affixes have been removed.(3) Is a root necessarily a free morpheme? Why?2.2.1 Two types of roots- Free rootIn English, many roots are free morphemes, such as black in black, blackboard, blacksmith.- Bound rootHowever, there are quite a number of roots which cannot exist on their own and thus belong to the class of bound morphemes. For example, ceive in receive, conceive, perceive, deceive; mit in permit, commit, submit; tain in retain, contain, maintain; cur in recur, occur, incur, etc.these roots cannot be used to form new words.2.2.2 Two types of affixesAffix is a collective term for the type of formative (构词成分) that can be used only when added to another morpheme.- Inflectional affixes (or inflectional morphemes) serve to expressthe following meanings:(1) plurality: e.g. -s in chairs, pens; -es in boxes, tomatoes;en in oxen.(2) the genitive case: e.g. ’s in boy’s, children’s.(3) the verbal endings: for example,a. -(e)s in words like eats, teaches shows the third personsingular present tense.b. -ing in words like eating, teaching shows the presentparticiple or gerund.c. -(e)d in words like worked, saved shows the past tense or pastparticiple.(4) the comparative and superlative degrees:e.g. -er in words like smaller, harder; -est in words like smallest,hardest.- Derivational affixes (or derivational morphemes)can be further divided into prefixes and suffixes.•(1) Prefixes are affixes before the root, e.g: unjust, rewrite.As a rule, most prefixes modify the meaning of roots, but not their parts of speech.task: list some prefixes that can modify the parts of speech.- en-(em-) as in words like embody, enrich- be- as in words like befriend, belittle- a- as in words like asleep, aside • (2) Suffixes are affixes after the root, e.g.: darkness, worker. By the addition of the suffix,the word is usually changed from one part ofspeech into another, e.g. liberation, modernize.2.3 Relationship between the two classifications of morphemesMorphemeIt is the minimal meaningful unit of language. Or it is the smallest functioning unit in the composition of words.a) Bound morphemes are morphemes which alone can be used as words .What is an allomorph?An allomorph is one of the variants of the same morpheme.语素/形位变体是同一个语素的不同形式。

Word --- A word is a minimal free form of a language that has a given sound and meaning and syntactic function.2. 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. The difference between sound and form result from 4 major factors.（At least 80%of the English words fit consistent spelling patterns）a）。

新编英语词汇学教程田贵森笔记1.What is polysemy?Having multiple meanings that are related.2.What are the two different ways of organising polysemous words? Explain them1)The diachronic approach begins with the primary meaning and then arrange the other meanings (derived meanings) in the order in which they developed.2)The synchronic approach begins with the most popular meaning (central meaning) and then arrange the other meanings (marginal meanings) in order of popularity.3.What are the two different ways in which polysemy develops? Explain them1)Radiation. Secondary meanings are independent from one another and are derived directly from the primary meaning.2)Concatenation. Secondary meanings are connected and derive from primary meaning through successive shifts of meaning from one secondary meaning to another.4.What is homonymy?Homonyms are works different in meaning but either identical both in sound or spelling or identical only in sound or spelling.5.Give an example of a perfect homonym, a homophone and a homograph1)perfect homonym 同音同形 date日期/date红枣2)homophone 同音异形 Knew/new, meet/meat3)homograph 异音同形 record(v.)/record(n.)6.Give an example of the rhetorical use of homonymyHi Jack （你好杰克）– hijack（打劫）7.What is the difference between polysemy and homonymy? Give an example to illustrate the difference1)Polysemy is about connection of meanings. Book can meana book as in “I read a book”, and “I book a hotel room”. The second meaning is related to the first one because in the past hotel staff will write the customers’ information on a book when reserving a room.2)homonymy is about form. Lie can mean not being honest or being in a horizontal position. These two meanings have the same form but no connection.8.Classify the following pairs of antonyms into complementaries (binaries), contraries (gradable) or converses (relational). Explain why1)Good/bad, contraries2)odd/even, complementaries3)above/below, converses4)clean/dirty, contraries5)remember/forget, complementaries?6)old/young, contraries7)before/after, converses9.What is hyponymy? Give an exampleThe meaning of a more specific word is included in that of a more general word.例Flower is the superordinate term, rose is the subordinate term.10.What is synonymy?Synonyms are words different in sound and spelling but nearly or exactly alike in essential meaning.11.What is the difference between absolute and near (relative) synonyms?1)Absolute synonyms – interchangeable in every way2)Near synonyms –similar in denotation but have different shades of meaning or different degrees of a given quality.。

词汇学名词解释1. Word --- A word is a minimal free form of a language that has a given sound and meaning and syntactic funtion.2. Morpheme --- A morpheme is the minimal significant element in the composition of words.3. Free morphemes or Content morphemes (Free root) --- They are morphemes that may constitute words by themselves : cat, walk.4. Bound Morphemes or Grammatical morphemes --- They are morphemes that must appear with at least one other morpheme, either bound or free : Catts, walk+ing.5. Bound root --- A bound root is that part of the word that carries the fundamental meaning just like a free root. Unlike a free root, it is a bound form and has to combine with other morphemes to make words. Take -dict- for example: it conveys the meaning of "say or speak" as a Latin root, but not as a word. With the prefix pre-(=before) we obtain the verb predict meaning "tell beforehand".6. Affixes --- Affixes are forms that are attached to words or word elements to modify meaning or funtion.7. Inflectional morphemes or Inflectional affixes --- Affixes attaches to the end of words to indicate grammatical relationships are inflectional ,thus known as inflectional morphemes.There is the regular plural suffix -s(-es) which is added to nouns such as machines, desks.8. Derivational morphemes or Derivational affixes --- Derivational affixes are affixes added to other morphemes to create new words.9. Prefixes --- Prefixes are affixes that come before the word, such as, pre+war.10. Suffixes --- suffixes are affixes that come after the word, for instance, blood+y.Derivational morphemes/ derivational affixes --- A process of forming new words by the addition of a word element. Such as prefix, suffix, combing form to an already existing word.Prefixation ---- is the formation of new words by adding prefix or combing form to the base. (It modify the lexical meaning of the base)Suffixation--- is the formation of a new word by adding a suffix or combing form to the base and usually changing the word-class of the base. Such as boy. Boyish (noun- adjective)11. Root --- A root is the basic form of a word which cannot be further analysed without total loss of identity.12. Opaque Words--Words that are formed by one content morpheme only and cannot be analysed into parts are called opaque words, such as axe, glove. 13. Transparent Words--Words that consist of more than one morphemes and can be segmented into parts are called transparent words: workable(work+able), door-man(door+man).14. Morphs--Morphemes are abstract units, which are realized in speech by discrete units known as morphs. They are actual spoken, minimal carriers of meaning.15. Allomorps--Some morphemes are realized by more than one morph according to their position in a word. Such alternative morphs are known as allomorphs. For instance, the morpheme of plurality {-s} has a number of allomorphs in different sound context, e.g. in cats /s/, in bags /z/, in match /iz/.16. Derivation or Affixation--Affixation is generally defined as the formation of words by adding word-forming or derivational affixes to stems. This process is also known as derivation.17. Prefixation--Prefixation is the formation of new words by adding prefixes to stems.18. Suffixation--Suffixation is the formation of new words by adding suffixes to stems.19. Compounding（Compositon）--Compounding is a process of word-formation by which two independent words are put together to make one word. E.g. hen-packed; short-sighted.20. Conversion--Conversion is the formation of new words by converting words of one class to another class. This process of creating new words without adding any affixes is also called zero-derivation. E.g. dry (a.)-->to dry.21. Back-formation-- is a process of word-formation by which a word is created by the deletion of a supposed affix. E.g. editor entered the language before edit.22. Abbreviation ( shortening )-- is a process of word-formation by which the syllables of words are abbreviated or shortened.23. Abbreviation includes four types : I. Clipped words II. Initialisms III. Acronyms IV. Blends.I. Clipped words--are those created by clipping part of a word, leaving only a piece of the old word. E.g. telephone-->phone, professional-->pro.II. Initialisms--are words formed from the initial letters of words and pronounced as letters. E.g. IMF/ai em ef/=International Monetary Fund.III. Acronyms--are words formed from the initial letters of word and pronounced as words. E.g. NATO/'neito/=North Atlantic Treaty Organization.IV. Blends--are words that are combined by parts of other words. E.g. smoke+fog=smog.24. Polysemy--The same word may have two or more different meanings. This is known as "polysemy". The word "flight", for example, may mean "passing through the air", "power of flying", "air of journey", etc.Two approaches to polysemy: Diachronic and SynchronicDiachronically, we study the growth or change in the semantic structure of a word , or how the semantic structure of a word has developed from primary meaning to the present polysemic state .Synchronically, we are interested in the comparative value of individual meanings and the interrelation between the central meaning and the secondary meanings.Two processes leading to polysemy: Radiation and concatenationRadiation : Semantically, radiation is the process in which the primary or central meaning stands at the center while secondary meanings radiate from it in every direction like rays.Concatenation : is a semantic process in which the meaning of a word moves gradually away from its first sense by successive shifts, like the links of a chain, untill there is no connection between the sense that is finally developed and the primary meaning.25. Homonyms--are generally defined as words different in meaning but either identical both in sound and spelling or identical『a.同一的，完全相同的』only in sound or spelling.26. Perfect Homonyms--are words identical both in sound and spelling,but different in meaning。

词汇期末复习（C1-C7）Chapter 1一、Word 词的定义(1) a minimal free form（最小的自由形式）(2) a sound unity(3) a semantic unity（meaning）(4) a form that can function alone in a sentence.（具有句法功能）二、V ocabulary词汇的定义All the words in a language make up what is generally known as vocabulary.一般来说，词汇指的是一种语言里所有单词的总和。

词的总和构成语言的词汇。

词与词汇之间的关系是个体与总体之间的关系。

三、Sound&Meaning发音和意义The connection between the sound (form) and meaning is arbitrary (任意的) and conventional.二者的关系是约定俗成、随意的四、Sound & Form发音和形式(1)The written form of a natural language is the orthographical（正字的）record of the oral form. 自然语言的书写形式是口语形式的书写记录。

(2)The reasons of differences occur between sound and form: 发音与形式不同的原因：①English alphabet was adopted from the Romans 英语字母表来自罗马②the pronunciation has changed more rapidly than spelling over the years. 发音改变快速③Differences created by professional scribes. 专业抄写员的不同④More differences brought by the continuing change of sounds and the standardization of spelling.发音不断变化，书写标准化。

何谓词汇学？不少学生误以为，词汇学就是“学词汇”，把词汇学与市场上编写的“突破词汇大关”的各种词汇手册联系起来。

然而，真正开始学习，发现完全是两回事，因此产生畏难情绪。

有的学生说，他们把《英语词汇学》看过数遍，书上讲的东西似乎都明白了，但参加考试，结果却不理想。

凡此种种，实际上集中于两个问题：一是词汇学属于什么性质的课程，它包括哪些内容？二是学词汇学，怎样才能收到好效果？本文就这两个问题谈几点意见。

一、《英语词汇学》的性质英语词汇学是一门有关英语词汇的学问，是普通高等院校英语专业普遍开设的专业知识课程。

因为这门课程实用性强，对学好英语语言很重要，所以被列为高等教育自学考试英语语言文学专业本科段选修课。

英语词汇学是专业理论课，它运用现代语言学的有关理论，研究英语语言中的词汇问题。

该课程介绍“词”的基本知识，讨论词的形态结构及构成方式，探讨词的意义及语义关系，阐述英语词汇的发展变化乃至相关的词典知识。

学习本课程的目的是对英语词汇具有比较系统、比较完整的知识，较深入地了解英语词汇的现状及其历史演变过程，并能对现代英语词汇发展中出现的各种词汇现象做出分析和解释，提高对英语词语的理解、阐释和综合运用的能力。

由此可见，词汇学绝对不是一般意义上的“学词汇”。

Acronyms IV. Blends.I. Clipped words--are those created by clipping part of a word, leaving only a piece of the old word. E.g. telephone-->phone, professional-->pro.II. Initialisms--are words formed from the initial letters of words and pronounced as letters. E.g. IMF/ai em ef/=International Monetary Fund.III.

NATO/'neito/=North Atlantic Treaty Organization.IV.Blends--are words that are combined by parts of other words. E.g. smoke+fog=smog.24. Polysemy--The same word may have two or more different meanings. This is known as "polysemy". The word "flight", for example, may mean "passing through the air", "power of flying", "air of journey", etc.*Two approaches to polysemy: Diachronic and SynchronicDiachronically, we study the growth or change in the semantic structure of a word , or how the semantic structure of a word has developed from primary meaning to the present polysemic state .Synchronically,we are interested in the comparative value of individual meanings and the interrelation between the central meaning and the secondary meanings.*Two processes leading to polysemy: Radiation and concatenationRadiation: Semantically, radiation is the process in which the primary or central meaning stands at the center while secondary meanings radiate from it in every direction like rays.Concatenation: is a semantic process in which the meaning of a word moves gradually away from its first sense by successive shifts, like the links of a chain, untill there is no connection between the sense that is finally developed and the primary meaning.25. Homonyms--are generally defined as words different in meaning but either identical both in sound and spelling or identical『a.同一的，完全相同的』only in sound or spelling.26. Perfect Homonyms--are words identical both in sound and spelling,but different in meaning。
