本文提出了语义的曲折性概念,认为如果一个语言结构所表达的意思不能直接从其字面义(包括成分义和成分之间的结构义)得到,则该结构具有语义上的曲折性。语义的曲折性体现在两个层面上,即成分义和整体义的关系层面和成分义之间的关系层面。曲折性是复合词语义的首要特性,是复合词和短语划分的决定性标准。本文把复合词词素之间的曲折性转化为可观察的语义框架,并主要运用曲折性标准对复合词和短语的划分作出了新的尝试。 This paper proposes the concept of tortuosity in semantics and holds that the structure has the semantic tortuosity if its meaning can not be obtained directly from its literal meaning (including its structural meaning). Semantic meanings are embodied on two levels, that is, the relational level between the meaning of meaning and the meaning of meaning. Zigzagging is the primary feature of the compound word semantics and the decisive criterion for compounding words and phrases. In this paper, the tortuosity between compound morphemes is transformed into an observable semantic framework, and a new attempt is made to divide the compound words and phrases mainly by the tortuous criterion.
