Motivation of words分类：onomatopoeic motivation, morphological motivation, semantic motivation, etymological motivation. Types of meaning: grammatical ~ & lexical ~; conceptual ~& associative ~(connotative~, stylistic~, affective ~, collocative ~,)Primary meaning is the only meaning that a word had when it was first created. Derived meanings are the meanings that a word gets from the primary meaning at different stages of its development in the course of time.同义关系Synonyms are words which share the same or nearly the same meaning with each other but different in sound and spelling. There are absolute synonyms and relative synonyms which result from borrowing, dialects and regional English, figurative and euphemistic use of words, coincidence with idiomatic expressions. There exists the difference between or among synonyms in terms of their denotation, connotation or application. Absolute synonyms or complete synonyms are words which are identical in meaning in all its aspects. Relative synonyms or near-synonyms are similar or nearly the same in denotation, but embrace different shades of meaning or different degrees of a given quality.3.Sources of Synonyms 1) Borrowing 2)Dialects and regional English 3) Figurative and euphemistic use of words 4) Coincidence with idiomatic expressions4.What are the characteristics of antonyms?1) Antonyms are classified on the basis of semantic opposition 2) A word which has more than one meaning can have more than one antonym. 3) Antonyms differ in semantic inclusion. 4) Contrary terms are gradable antonyms, differing in degree of intenisty, so each has its own corresponding opposite.5.同形同音异义关系Homonymy is one of the features of words that a word is different in meaning from another, but either identical both in sound and spelling or identical only in sound or spelling with the other Homonyms generally fall into three classes: perfect homonyms (same name); homographs (same spelling) and homophones （some sound）. Perfect homonyms are those words identical both in sound and spelling, but different in meaning. Homophones refer to the words identical only in sound but different in spelling and meaning6.上下义关系:Hyponymy deals with the relationship of semantic inclusion. That is, the meaning of a more specific word is included in that of another more general word. Superordinates refer to some general words; subordinates denote those more specific words. Hyponymy can be described in terms of tree-like graphs, with higher-order superordinates above the lower subordinates. But their status either as superordinate or subordinate is relative to other terms. For example, horse, dog, pig are subordinates in relation to animal, but superordinates of mare, hound and boar, Animal itself becomesa subordinate of creature. And creature in turn becomes7.词义变化的种类There are five types of meaning, changes: extension, narrowing, degradation, elevation, and transfer among which extension and narrowing are the most common. Changes in meaning can be accounted for from extra-linguistic factors (historical reason, class reason, and psychological reason) and intra-linguistic factors (shortening, the influx of borrowing, and analogy).8.词义的扩大Extension is a process by which a word with a specialized sense is generalized to covera broader or less9.Definite concept. Compare the following；词义的缩小Narrowing is a process by which a word of wider meaning acquires a specialized sense；词义的升华Elevation is a process by which a word moves from a derogatory or neutral sense to a neutral and/or appreciative sense；词义的降格Degradation is a process by which a word of reputation slides into a pejorative use,；词义的转移Transfer is a process by which a word denoting one thing changes to refer to a different but related thing. Paper serves as an example. This word formerly denoted an African plant papyrus, which wasonce used to make paper. In modern times, paper is made from rags, wood, straw and the like, but the product has retained the same name. There is associated transfer. There are other kinds of transfer, such as, concrete to abstract, abstract to concrete and transfer of sensation.10.语境的种类:非语言语境。

语言语境：词汇语境和语法语境。

There are two types of contexts: linguistic context and extra-linguistic (or non-linguistic context). Extra-linguistic context refers to those situations and features which are not directly a part of the language in use but which either contribute in conveying a message or have an influence on language use. Linguistic or Intra-linguistic context is further subdivided into lexical context and grammatical context. By lexical context we mean the words that occur together with the word in question. By grammatical context we mean that the meanings of a word may be influenced by the structure in which it occurs.11.语境的作用：Three major functions of context: elimination of ambiguity, indication of referents, provision of clues for inferring word-meaning. Context an be summed up as follows:1) definition 2) explanation 3) example 4) synonymy 5) Antonymy 6)hyponymy 7) relevant details 8) word structure12.英语习语的特点The characteristics of idioms include semantic unity and structural stability.13.英语习语的分类According to the criterion of their grammatical functions, we classify them into idioms nominal in nature, idioms adjectival in nature, idioms verbal in nature, idioms adverbial in nature, and sentence idioms. The stylistic features are characterized with colloquialisms, slang, and literary expressions.14.英语习语的使用The use of idioms involves their stylistic features, rhetorical features , and variations of idioms.15.英语习语的修辞色彩The rhetorical features of idioms are represented with phonetic manipulation ( alliteration 头韵法and rhyme叠韵) , lexical manipulation ( reiteration复用, repetition重复and juxtaposition反义词叠用), figures of speech ( simile明喻, metaphor暗喻, metonymy转喻, synecdoche借代, personification拟人, euphemism委婉)16.英语习语的变异形式In the variations, addition, deletion, replacement, position-shifting and dismembering are involved in the changes in idioms constituents .17.Associative meaning : 1) associative meaning is the secondary meaning supplemented to the conceptual meaning. 2)It differs from the conceptual meaning in that it is open-ended and indeterminated. 3)It is liable to the influence of such factors as culture , experience, religion, geographical region, class background,education, etc. 4)Associative meaning comprises four types : connotative, stylistic, affective, and collocative.词典的种类There are four types of dictionaries with their features mentioned in this parts: (1) monolingual and bilingual dictionaries, (2) linguistic and encyclopedic dictionaries, (3) unabridged, desk and pocket dictionaries, (4) specialized dictionaries. A monolingual dictionary is a dictionary which is written in one language.18.A bilingual dictionary is one in which two languages are involved.19.A linguistic dictionary is a dictionary which aims at defining words and explaining their usages in the language.20. An encyclopedic dictionary is one in which encyclopedic information is provided along with the general information as in a linguistic dictionary.21.An encyclopedia is a dictionary which only provides encyclopedic information concerning each headword.22.An unabridged dictionary is an unshortened dictionary with at least 200,000 headwords that can supply a great quantity of basic, information about a word.23.A desk dictionary is a medium-sized dictionary containing words ranging from 50,000 to 150,000.24.A pocket dictionary is a dictionary which has about 50,000 entries or fewer.第一章37.What is word ?词具有哪些特点？词的特点也就是对词的名词解释。
