语言学知识_语义学

语义学一.语义学(Semantics)的定义:研究语言单位的意义,尤其是词语和句子的意义。
二.词汇意义(Lexical Meaning):1)意义与指称(sense and reference):意义与指称是语言研究中的两个术语,它们之间既相互联系,又相互区别。
意义(sense)是一系列抽象语义特征的集合,与语境无关,可以在字典中查到。
而指称(reference)是语言形式在现实物质世界中所指的事物;它涉及语言形式与非语言的现实世界之间的关系。
意义与指称是意义的两个相关但不同的方面,例如“morning star”和“evening star”的意义虽然不同,但其指称一样,都指代天空中的同一颗星星。
2)外延意义(denotative meaning):指词语所指称的外部世界的事物、状态、抽象情感。
例如:dog(狗)的外延意义是指“一种四肢、有毛、会汪汪叫的哺乳动物”,这种意义在任何国家、任何时代都不会改变。
3)内涵意义(connotative meaning):指源于语言使用者的个人经历、情感、评价、语境等外部因素的意义。
例如dragon一词,在汉语文化中象征着“高贵”、“权利”,但在某些英语国家文化中,其内涵意义则为“残暴”和“邪恶”。
三.意义关系(Sense Relationship):1)同义关系(Synonymy):方言同义词(Dialectal synonyms):意义相同但方言有差异的词,例如:autumn(BrE)= fall(ArE)。
文体同义词(Stylistic synonyms):意义相同但在文体上或者正式程度上有差别的词,例如:buy(较为随意)——purchase(较为正式)。
搭配同义词(Collocational synonyms):指意义上相同,但是搭配不相同的词。
例如:provide和supply,provide sth. for sb.和supply sth. to sb.在情感或评价意义方面存在差异的同义词(Synonyms with different emotive or evaluative meaning):意义相同,但在情感或评价意义方面存在差异的词,例如:politician (政客)含贬义色彩,statesmen(政治家)含褒义色彩。

公共基础知识语义学基础知识概述

《语义学基础知识综合性概述》一、引言语义学作为语言学的一个重要分支,研究语言的意义,对于我们理解和运用语言起着至关重要的作用。
从日常交流到文学创作,从学术研究到人工智能,语义学的影响无处不在。
本文将全面阐述语义学的基础知识,包括基本概念、核心理论、发展历程、重要实践以及未来趋势。
二、基本概念1. 语义的定义语义是指语言所表达的意义,包括词汇意义、句子意义和语篇意义等。
它涉及到语言符号与所指代的事物、概念、情感之间的关系。
2. 语义单位语义学中常见的语义单位有词素、词汇、短语和句子等。
词素是最小的有意义的语言单位,词汇是由词素组成的词语,短语是由词汇组成的语言片段,句子则是表达完整意义的语言单位。
3. 语义特征语义特征是指词汇或语言单位所具有的特定意义属性。
例如,“红色”这个词汇具有“色彩鲜艳”“暖色调”等语义特征。
语义特征可以帮助我们区分不同的词汇和语言单位,理解它们的意义和用法。
三、核心理论1. 指称理论指称理论关注语言符号与外部世界的关系,探讨语言如何指代现实中的事物和概念。
指称可以分为直接指称和间接指称。
直接指称是指语言符号直接指代具体的事物或概念,如“苹果”这个词汇直接指代一种水果。
间接指称则是通过隐喻、转喻等修辞手法来指代事物或概念。
2. 涵义理论涵义理论研究语言符号所蕴含的意义和情感。
涵义可以分为概念涵义和情感涵义。
概念涵义是指词汇或语言单位所表达的客观概念,如“汽车”这个词汇的概念涵义是一种交通工具。
情感涵义则是指词汇或语言单位所表达的主观情感和态度,如“美丽”这个词汇的情感涵义是积极的、赞赏的。
3. 语义场理论语义场理论认为词汇不是孤立存在的,而是处于相互关联的语义网络中。
同一语义场中的词汇具有相似的意义和用法,它们之间的关系可以是同义关系、反义关系、上下义关系等。
例如,“红色”“蓝色”“绿色”等词汇属于颜色语义场,它们之间是并列关系。
4. 语用学与语义学的关系语用学研究语言在实际使用中的意义和效果,与语义学密切相关。
语义学笔记整理

语义学笔记整理第⼀章作为语⾔学⼀个分⽀的语义学语义学的建⽴以法国学者⽶歇尔·布勒阿尔1897年7⽉出版《语义学探索》为标记。
该书1900年翻译为英⽂“语义学:意义科学的研究(Semantics:Studies in the Science of Meaning)”。
这本专著材料丰富,⽣动有趣,重点在词义的历史发展⽅⾯,兼顾词汇意义和语法意义。
全书共三编:1,讲词义变化的定律,介绍变异、扩散、类推等概念;2,讲如何确定词义,介绍释义、⽐喻、多义、命名等;3,讲词类、词序、组合规则等,涉及语法意义。
除了语⾔学的语义学,还有逻辑学的语义学,哲学的语义学,还有⼼理学家对语义的研究。
a,逻辑学的语义学是对逻辑形式系统中符号解释的研究,⼜称“纯语义学”,对象并⾮⾃然语⾔的语义。
b,哲学的语义学围绕语义的本质展开涉及世界观的讨论。
“语义学”或“语义哲学”⼜是本世纪前半叶盛⾏于西⽅的⾄今仍有影响的⼀个哲学流派的名称。
c,⼼理学家研究语义,主要是想了解⼈们在信息的发出和接收中的⼼理过程。
d,语⾔学的语义学把语义作为语⾔(乃⾄⾔语)的⼀个组成部分、⼀个⽅⾯进⾏研究,研究它的性质,内部结构及其变异和发展,语义间的关系等等。
布勒阿尔的书给语义的发展以重要地位,声称研究语义的变化构成了语义学。
同时它把语义限制在“词语”的意义上,主要是词义上。
这两个特点⼀直贯穿在他以后半个多世纪的若⼲代表性著作⾥。
继布勒阿尔之后,⼀部有世界影响的语义学专著是两位英国学者奥格登和理查兹合写,1923年出版的《意义的意义》(The Meaning of Meaning)。
这两位学者还曾共同创制了后来遭到各种⾮议的“基本英语”(Basic English).从30年代到50年代后期,以美国布龙菲尔德的理论为代表的结构主义统治着西⽅语⾔学。
布龙菲尔德认为,研究语义学的⼈须是万事皆通的博学者,语⾔学家⽆法担此重任,语⾔学家关⼼的是语⾔的形式。
语义学汇总

一、语义学视角下语义的表现(一)王寅教授的分析(1)说话人意义(speaker‟s meaning), 受话人的意义(hearer‟s meaning)[语言交际过程中参与者的角色分析](2)自然意义(natural meaning)和非自然意义(unnatural meaning)(3)词素义(morpheme meaning), 词义(word meaning), 句义(sentence meaning), 话词义(utterance meaning), 语篇义(discourse meaning)(4)内涵义(intensional meaning )与外延义(extentional meaning)[从哲学和逻辑学角度](5)概念意义和附加意义(conceptual meaning and added meaning)(二)、Leech 对意义的区分七种Leech recognizes seven types of meaning in his Semantics1)Conceptual meaning :logical, cognitive, or denotative content2)Connotative meaning: What is communicated by virtue of what language refers to3)Social meaning: What is communicated of the social circumstances of language use4)Affective meaning: What is communicated of the feelings and attitudes of the speaker/writer5)Reflected meaning : What is communicated through association with another sense of the same expression6)Collocative meaning: What is communicated through association with words which tend to occur in the environment ofanother word7)Thematic meaning: What is communicated by the way in which the message is organized in terms of order andemphasis.以下为对上述的解释1、自然意义,非自然意义Natural meaning and non-natural meaningNatural meaning and nonnatural meaning is put forward by Grice in his famous article “Meaning”.As for natural meaning, there is the evidential relationship between a cause and its effect. An example of natural meaning is “Those spots mean measles.” “x means y” is related to “x shows that y,” “x is a symptom of y” and “x lawfully correlates with y”. Those spots on little Jimmy do not really mean measles in natural meaning, if Jimmy does not have measles, even if the spots typically correlate with measles.Nonnatural meaning pertains to language and communication. It means words and speakers. On nonnatural s ense, “x means y” is closer to “x says/asserts that y”, “x expresses y”. And when “x means y” is the case, it will usually be true that someone, or some group, means something by x. In nonnatural sense, it can be true that “x means y” even though x obtains when y is not the case. Thus our speaker might indeed have meant that you should bring more whisky, when in reality you should not: his meaning it, in nonnatural sense, does not make it so.In Grice‟s opinion, nonnatural meaning is used to induce some bel ief in hearer. More than that, it is used to induce the belief by getting the addressee to recognize the intention to induce a belief: in meaning something, then speaker does not merely cause the hearer to have a belief, he/she overtly gives the speaker a reason to believe, the reason being that he/she wants the speaker to believe. Thus what a person means, in the nonnatural sense, comes down to his/her complex mental states, especially intentions.2、关于听话人,说话人The Speaker and the ListenerTo ensure smooth communication between the speaker and the listener, it is important to nail down the role of them and the interaction between them. Some basic linguistics theory, such as Speech Act Theory, the Cooperative Principle, Conversational Implicatures, the Politeness Principle, atc.will help learners to well understand the role of the speaker and the listener.Speech act is actions performed via utterances. In English, it is commonly given more specific labels, such as apology, complaint, compliment, invitation, promise, or request. These descriptive terms for different kinds of speech acts apply to the speaker's communicative intention in producing an utterance. The speaker normally expects that his or her communicative intention will be recognized by the hearer. Both speaker and hearer are usually helped in this process by the circumstances surrounding the utterance.We know that quite often a speaker can mean a lot more than what is said. The problem is to explain how the speaker can manage to convey more than what is said and how the hearer can arrive at the speaker‟s meaning. H. P. Grice believes that there must be some mechanisms governing the production and comprehension of these utterances. He suggests that there is a set of assumptions guiding the conduct of conversation. This is what he calls the Cooperative Principle (CP).According to Grice, conversational implicatures can arise from either strictly and directly observing or deliberately and openly flouting the maxims, that is, speakers can produce implicatures in two ways: observance and non-observance of the maxims. The least interesting case is when speakers directly observe the maxims so as to generate conversational implicatures. If the hearer wants to accurately export the conversational implicatures, he or she should know something about the the following aspects: 1)conventionality implicatures of the utterance; 2)cooperative principle and criteria; 3)the context of the utterance; 4)some common background knowledge of the speaker and the listener.In most cases, the indirectness is motivated by considerations of politeness. Politeness is usually regarded by most pragmatists as a means or strategy which is used by a speaker to achieve various purposes, such as saving face, establishing and maintaining harmonious social relations in conversation, thus to promote better communication between the speaker and the listener.3、句义,词义,话语意义,命题意义,篇章意义从哲学方面以及语言学方面对其进行分析;它们在不同语境中状态;结合法律举例1) Word meaningWord is a unit of expression that has universal intuitive recognition by native speakers, whether it is expressed in spoken or written form.Sense and reference are two terms often encountered in the study of word meaning. They are two related but different aspects of meaning. Sense is concerned with the inherent meaning of the linguistic form. It is the collection of all the features of the linguistic form: it is abstract and de-contextualized. Reference means what a linguistic form refers to in the real physical world; it deals with the relationship between the linguistic element and the non-linguistic world of experience. Obviously, linguistic forms having the same sense may have different references in different situations. On the other hand, there are also occasions, when linguistic forms with the same reference might differ in sense. A very good example is the two expressions “morning star” and “evening star”. These two differ in sense but as a matter of fact, what they refer to is the same: the very same star that we see in the sky.According to Wittegenstein, words like tools, the meaning of word depends on the usage of the word. In another word, the meaning of word depends on the function of the word. The meaning of a word rests with the usage of the word in a language. Words are different tools in language. These tools are characterized by their usage. Sometimes, he did not see words as tools, however, he said directly: languages are tools. The different concepts in language are different tools.2) Sentence Meaning:(句子意义是构成句子的词汇意义和结构意义共同作用的结果)The meaning of a sentence is often studied as the abstract, intrinsic property of the sentence itself in terms of predication. It is obvious that the sentence meaning is connected with the meaning of the words which constitute the sentence; but it is stillclear that the sentence meaning is not the totality of the meanings of the component words because the syntactical structure of the sentence also plays a role in determining the sentence meaning. That is to say, the meaning of a sentence is a product of both lexical and grammatical meaning. Lexical meaning is the de-contextual denotation of the words which is defined in the dictionary, while the grammatical meaning is abstract meaning represented by the grammatical structures of the words.
