What is lexical meaning and what is grammatical meaning?
E.g. The English word tourists contain three morphemes. One minimal unit of lexical meaning is tour and another unit of lexical meaning is –ist which means person who does something. The third minimal unit –s has grammatical meaning indicating plurality.
• Bound morphemes are actually affixes. 黏着语素实际上 就是词缀。
• 词缀本质上是黏着的。Affixes are naturally bound. All affixes in English are bound.
• ——词缀是那些只能附着于另一个语素上的一类语素
• Inflectional affixes serve to indicate grammatical relations.
• Inflectional affixes are not used to produce new words, but rather to show aspects of the grammatical functions of a word.
自由语素 vs黏着语素
• 像tour, chair这种能够独立构词的语素，我 们称之为自由语素。 Those which may make up words by themselves are free morphemes. Free morphemes can stand by themselves as words.

2.2 Morpheme
Morpheme: the smallest meaningful unit of a language. It cannot be divided without altering or destroying its meaning. Morpheme is the smallest unit of language in terms of the relationship between expression and content, a unit that cannot be divided into further smaller units without destroying the meaning.
Morphology is the study of the internal structure of words and rules by which words are formed. It is generally divided in two fields: (1) Inflectional morphology: the study of inflections. (2) Derivational morphology: the study of word-formation.
be realized in different contexts as the alternate shapes of phonetic forms as : {-s, z, -iz, -ai, -I, -n, -∮} , which are called the allomorphes of the same morpheme{-s}

3) Closed-class words vs. open-class words: Closed-class: a word whose membership is fixed or limited.
New members are not regularly added. Pronouns, prepositions, conjunctions, articles, etc. Open-class: A word whose membership is in principle infinite or unlimited. Nouns, verbs, adjectives, adverbs Note: The distinction is not quite as clear-cut as it seems. Prepositions: regarding, throughout, out of, according to, with regard to, in spite of, be means of ; Auxiliary verbs

• Lexicology relies on morphology for information about construction of words, parts of words and distinction between different types of words.
• The study of lexicology owes a good deal and is also useful to three disciplines:
• (a) morphology

常规采用的FAB分型法简单易行， 至今仍是AL诊断分型的基本手段。然 而，白血病细胞高度异质性，形态上 复杂多变，尤其对分化差或混合性白 血病单凭细胞形态学分型有一定困难 。加之，细胞水平的观察属于直观判 断，其准确程度与检测人员的经验有 关，带着主观因素，其诊断符合率大 约 60%～70%。

1986年FAB协作组提出了MIC分型法
• 形态学 (morphology，M)、 • 免疫学 (immunology，I)、 • 细胞遗传学( cytogenetics，C)，
该分型法以形态学为基础、免疫学 和细胞遗传学作补充，相互结合，使分 型更趋精确。

随着免疫学的发展，人们对白细胞分 化和白血病细胞的来源认识不断完善。 白血病细胞能保持正常血细胞各个分化时 期的抗原特征，较准确地鉴别AL的类型、 指导治疗判断预后。1982年11月在巴黎召 开第一届人类白血病分化抗原会议，同意 并批准使用分化群（clusters of differentiation，CD）作为白细胞分化抗 原的命名。以后又陆续新增加了多种CD， 并在分化抗原的功能研究方面获得许多新 的突破。

chapter 3 Morphology 英语专业语言学PPT


Derivational and inflectional morphemes (p.55)
Some derivational morphemes change the grammatical category of words (or grammatical class of words) and others
➢ the smallest unit in terms of relationship between expression and content,
➢ a unit which cannot be divided without destroying or drastically altering the meaning, whether it is lexical or grammatical.
When the root of the word is a free morpheme, we say the word has a free root, such as e.g. hopeful, interpersonal
When it is a bound morpheme, we say the word has a bound root, such as e.g. precede, receive, submit, retain, recur
The identification of words
(2) Relative uninterruptibility(相对的不可 隔 断 性 ): new elements are not to be inserted into a word even when there are several parts in the word. (i.e. outlaws, touch-me-not)

前缀和后缀
前缀和后缀都是从单词 开头或结尾添加的符号。
中缀
中缀是添加在单词内部 的符号，一般用于词汇 的缩略或组合。
复合词
复合词由两个或多个单 词组成而成，例如“公共 汽车”、“黑板报”。
形态框架
形态框架的定义
形态框架是形态学研究中对 单词内部构词规则的一种体 系化总结。
形态框架的结构
词素和词根
形态框架结构包括意义、形 式、位置、状态等基本要素。
课件3._morphology
学习单词的构词法，深入了解派生和屈折的概念，以及词法规则，并通过实 例了解应用。
什么是形态学
形态学的起源
形态学起源于对单词的构成 和意义的研究。
形态学的定义
形态学是研究单词形态结构 和词根的学问。
形态学的意义
了解形态学可以帮助我们更 好地理解语言的运用方式。
单词的构词法
词素是基本意义的单位，词 根是构成单词的基本成分。
派生和屈折
1
派生
派生是指通过加词缀等方式构成新单词的过程。
2
屈折
屈折是指通过变化单词形式来构成语法所需格式的过程。
3
不同
派生和屈折的区别在于派生重点在于意义的变化，而屈折则是语言规范的一部分，涉及到正式书面语言的正确性。
2 多样性
不同的语言和词汇系统有着不同的词法规则，需要进行学习和掌握。
3 应用广泛
在语言使用中，遵循词法规则可以避免误解和错误。
应用举例
中文词语
• 手机号码： 手机 +号码 • 安保措施： 安全 +保护方式 • 月光族： 收入不稳定 +消费型
英文词汇
• Unfriendly：Un +friendly • popularize：popular +-ize • Unicorns：uni- +corn +-s
