1 Basic Concepts 基本概念 1.1 the definition of a word

（The definition of a word comprises the following points: (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. A word is a minimal free form of a language that has a given sound and meaning and syntactic function.）

1.2 sound and meaning ：symbolic connection is almost always arbitrary and conventional. A dog is called a dog not because the sound and the three letters that make up the word just automatically suggest the animal in question.

1.3 sound and form ：

1. No enough letters: alphabet from Latin

2. Pronunciation changed more rapidly

3. Early scribes: change spelling for easier recognition

4. Borrowing: different rules of pronunciation and spelling all national character 全民性

2 Development

It is assumed that the world has approximately 3, 000 (some put it 5, 000 ) languages, which can be grouped into roughly 300 language families on the basis of similarities in their basic word stock and grammar. Prussian 普鲁士语

3 Word Formation 3.1 Morphemes 词素

Definition: These minimal meaningful units are known as morphemes. In other words, the morpheme is \.词素是―构词中最小功能单位‖。 3.2 Allomorphs 语素变体

Morphemes are abstract units, which are realized in speech by discrete units known as morphs. 'They are actual spoken, minimal carriers of meaning'. The morpheme is to the morph what a phoneme is to a phone. 词素是一个音素发音的语素。词素是真正能发音的最小的意义载体。 monomorphemic words：can stand by themselves and function freely in a sentence. morpheme 单语素词 在句子中独立起作用 allomorphs：the alternative morphs of the same morpheme 词素变体 可替换语素（音标）的相同词素

free morpheme —— free root Independent 独立

自由语素 自由词根 free grammatical units 自由的语法单位 3.3 Types of Morphemes complete meanings 完整的意义

bound root ：fundamental meaning

4 Word-formation

affixation (30%-40%) 词缀法（30%--40% ）

compounding (28%-30%) 复合法(28% -30% ）

conversion (26%) 转化法（26% ） Word formation clipping 删节

shortening (8%-10%) 缩略法（8% -10%） acronymy 首字母缩略法 构词的方式

blending and other means (1%-5%) 拼缀法和其他方法（ 1 ％-5% ）

prefixation 前缀法 —— before the word, modify the meaning 前置，改词意

4.1 Affixation 词缀法 falls into two subclasses（子类）: suffixation 后缀法 —— after the word, change word class 后置，改词性

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, for new words created in this way are derived from old forms. The words formed in this way are called derivatives.

词缀法可定义为通过给词干加结构词词缀或派生词缀构成新词的一种构词方法。用这种方法构成的词叫派生构词。因为通过这种方式创造的新词是从旧词 派生而来。通过这种方式造出的词叫做―派生词‖。 Negative prefixes 否定前缀(a-, an-, dis-, in-, non-, un-) Reversative prefixes 逆反前缀(de-, dis-, un-) Pejorative prefixes 贬义前缀(mal-, mis-, pseudo-) Prefixes of degree or size程度大小前缀(arch-, co-, hyper-, mini-, out-, over-, sub-, under-, ultra-, super-, sur-)

4.1.1 Prefixation 前缀法 Prefixes of orientation and attitude 倾向态度前缀(anti-, contra-, counter-)

（we shall classify prefixes on a semantic basis 将前缀分为九类）

into nine groups 我们可以在语义基础上

Prefixation is the formation of new words by adding prefixes to stems. Prefixes do not generally change the word-class of the stem but only modify its meaning. 前缀法是在词干上加上前缀构词的一种方法，前缀一般不改变词干的词类，只对词干的意义进行修饰。

Locative prefixes 方位前缀(fore-, inter-, sub-, super-, trans-)

Prefixes of time and order 时间顺序前缀(ex-, fore-, pre-, post-, re-)

Number prefixes 数字前缀(bi-, di-, multi-, poly-, semi-, demi-, tri-, uni-, mono-) Miscellaneous prefixes 多种前缀(auto-, extra-, neo-, paleo-, pan-, proto-, tele-, vice-)
