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.
Chapter 1--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
The basic 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) 4 Types 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
Chapter 2 the 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 prefix bound derivational affix suffix 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.
Chapter 4 Word-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
2.Compounding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
