同义复词是由两个具有同义关系的词素并列而成的复合词，属于并列式复合词中的一个重要类型。每个同义复词内部都含有两个构词词素。二者之间的关系是：结构上，是并列式；语义上，是同义的。同义复词的词义和两个词素的词素义之间具有对应关系。

根据以上原则，从《现代汉语词典》（第 7 版）中一共提取了现代汉语共时平面仍在使用的 3160 个同义复词，作为研究对象，并以词典释义法、义素分析法、动态语境分析法、字形探源法为语义分析的主要方法，结合微观与宏观、历时与共时的分析范式，从多个角度就词的产生、词义特点、书写形式等方面进行了具体描写和细致分析。

绪论部分阐述了选题缘由及意义，分析了并列式复合词及同义复词的研究现状，梳理了同义复词产生原因、发展及相关问题的研究成果。

文章主体内容包括三个组成部分：微观分析部分是同义词素的意义分析，微观与宏观相结合的部分是词与构词词素间关系分析，宏观分析部分是复合词词际关系分析。

微观分析部分主要对比两个构词词素的意义与功能上的异同。通过分析得出，同义词素在意义上“大同小异”：“同”体现为核心语义特征、语法意义相同；“异”体现在附加语义特征、词素义在意义历时演变中所处的地位不同。同义词素在功能上也不尽相同，体现为能否自由运用、构词能力是否存在差异等。

微观和宏观层面的综合分析部分主要梳理了构词词素和词的关系，分析了语法意义、词汇意义、色彩意义、语用功能的差异。同义复词两个词素意义相似度高，看似语义冗余现象，但发展到现代汉语阶段，大部分词和词素意义均发生了较大变化。因此，单音节词素从语义、功能和语用上并不能等同或代替双音节复合词。通过分析得出，词素与词的语法意义差异较小，一致性可达 88%。词素和词的词汇意义差异较大：关于词素和词在词汇意义上的关系类型，单义词和词素的关系共有九类；具有两个义项的多义词和词素的关系总结为七类；具有三个及以上义项的多义词和词素的关系较为复杂。词素和词的色彩意义差异较小，词素的色彩意义对词义具有直接影响。同素同义的词素和词在功能上也有差异，多呈互补状态。

宏观分析部分主要依据语义特点、形式特点对同义复词进行分类，考察了不同类型中词义和词素义内在关系上的不同特点。语义上的分类包括同义关系、近义关系、反义关系；形式上的分类包括同族词、同音同形词、异音同形词、异形词、同素逆序词。对同义复词及其同素逆序形式的分析是其重点，分别从义项数量、词汇意义、语法意义、色彩意义、使用频率五个方面展开。这五个方面特点完全一致的同素逆序词数量较少，比较而言，语法意义一致的占比较高；义项数量、词汇意义、色彩意义一致的占比次之；使用频率一致的占比最低。同义复词及其同素逆序形式很少有两种形式都常用的情况。

应用价值研究从词典编纂角度， 对词及词素的释义问题进行分析，并就同义复词和同义词素的释义应如何改进和完善的问题，结合实例提出了看法。

结语部分总结了全文，指出了主要创新点、研究的不足，以及下一步研究方向。

A tautological compound is formed by two morphemes with synonymous relations, belonging to an important type of juxtaposed compound. Each tautological compound contains two forming morphemes. The relationship between the two morphemes is: structurally, parallel; semantically, synonymous. There is a correspondence between the meaning of tautological compound and the meaning of the two morphemes.

According to the above principles, 3160 tautological compounds that are still used in the synchronic plane of modern Chinese are extracted from the “Modern Chinese Dictionary”(7th edition) as the research object, and the dictionary interpretation method, sememe analysis method, dynamic context analysis method and the source-searching method are the main methods of semantic analysis. Combining the analysis paradigms of micro and macro, diachronic and synchronic, specifically descript and meticulously analysis the characteristics of word meaning, the writing form etc. from multiple perspectives on the generation of words.

The introduction part mainly elaborates the reason and significance of the topic selection, analyzes the research at this stage of juxtaposed compound and tautological compound, and combs the causes, development and related research results of tautological compound.

The summary content part mainly determines the research object, defines the tautological compound, and classifies from the aspects of word generation, word meaning characteristics, writing form and so on.

The main content of the article includes three components: the micro-analysis part is the analysis of the meaning of synonyms morpheme, the micro-macro part is the analysis of the relationship between words and forming morphemes, and the macroanalysis part is the analysis of the inter-word relationship of tautological compound.

The micro-analysis part mainly compares the meaning and function of the two forming morphemes. Through analysis, it can be concluded that synonymous elements are “big similarities and small differences” in meaning: “identity” is reflected in the core semantic features and the same grammatical meaning; “different” is reflected in the different positions of additional semantic features and morpheme meanings in the evolution of meaning over time. Synonyms morpheme are also different in function, reflected in whether they can be used freely and whether there is a difference in word formation ability, etc.

The comprehensively analysis at the micro-macro part mainly combs the relationship between forming morphemes and words, and analyzes the differences in grammatical meaning, lexical meaning, color meaning, and pragmatic function. Two morphemes of the tautological compound have high similarity in meaning and seem to be a phenomenon of semantic redundancy. However, most modern words and morpheme meaning have changed significantly in modern Chinese stage. Therefore, singlesyllable morphemes cannot be equivalent to or replacement of two-syllable compound in terms of semantics, function and pragmatics. According to the analysis, the grammatical meanings between morphemes and words are small, and the consistency can reach 88%. The lexical meanings of morphemes and words are quite different. With regard to the relationship between morphemes and words in the lexical sense, there are nine types of relations between morphemes and monosemic words. The relationship between morphemes with polyseme words with two meanings is summarized into seven types, the relationship between morphemes and polysemous words with more than three meanings is more complicated. The difference in color meaning between morphemes and words is small, and the color meaning of morphemes has a direct impact on the meaning of words. Free morphemes and tautological compound having a synonym relationship also have different functions, and are mostly complementary.

The macro-analysis part mainly classifies the tautological compound according to the semantic characteristics and formal characteristics. The different characteristics of the internal relations between the meanings of word and morpheme in different types are investigated. Semantic classifications include synonymous relations, synonymous relations, and antonym relations; formal classifications include cognate words, homophones which have same sound, homophones which have different sound, heteromorphic words, allotropy words. The analysis of tautological compound and its allotropy words is the key point, starting from five aspects: the number of meaning items, lexical meaning, grammatical meaning, color meaning, and frequency of use. The number of allotropy words with identical characteristics in these five aspects is small. Comparatively speaking, most allotropy words which has the same grammatical meaning; the semantic items, vocabulary meaning, and color meaning of allotropy words are less similar; the frequency of the same frequency has the biggest difference. Tautological compound and their reverse order forms rarely have both forms commonly used.

The applied value part analyzes the interpretation of words and morphemes from the perspective of dictionary compilation. Combining with examples, puts forward views on how to improve and perfect the interpretation of tautological compound and synonyms morpheme

The concluding part summarizes the full text, and points out the main innovations, research deficiencies, and the next research direction.
