Componential analysis，指语素分析、成分分析，或者语义成分分析法等，英语定义如下：

1、Componential analysis 语义成分分析法定义

Componential analysis is a method of semantic analysis based on the assumption that the meaning of words can be adequately described by a set of primitive semantic features.

语义成分分析法是研究语义的一种重要方法,是结构语言学的对分法在语义研究中的具体应用，前提条件是词汇语义能够满足结构需要。

2、Componential analysis 语义成分分析法举例说明

bachelor = [+ MALE], [+ MATURE] or

鳏夫可以划分为二个语义场：男性+成年人

spinster = [– MALE], [+ MATURE] or

剩女可以划分为二个语义场：女性+成年人

boy = [+ MALE], [– MATURE] or

男孩可以划分为二个语义场：男性+未成年人

girl = [– MALE] [– MATURE] or

女孩可以划分为二个语义场：女性+未成年人

child = [+/– MALE] [– MATURE].

孩子可以划分为二个语义场：男性/女性+未成年人

将词汇划分为多个语义场【以上只是划分为二个语义场；其实，语义场划分越细致，甄别特征越明显】，可以甄别词汇语义在哪个层次是相同的，哪个层次是不同的；这样可以在不同语境中，区别词汇同义、近义、反义的关系，把握识别词汇正确语义，提高运用词汇质量和精度。

3、Componential analysis语义成分分析法说明

In other words, the word girl can have three basic factors (orsemantic properties): human, young, and female. Another example, being edible is an important factor by which plants may be distinguished from one another. To summarize, one word can have basic underlying meanings that are well established depending on the cultural context. It is crucial to understand these underlying meanings in order to fully understand any language and culture.

英语词汇都有语义层次或类别，比如相同之处都是人类；不同之处在于划分类别不同，+号表示具备某种属性；– 号表示不具备；比如，单词bachelor【单身狗】；spinster【剩女】都指未婚男女；语义成分分析法将这二个词分解为语义类别，分别是bachelor：人类-男性-未婚；spinster：人类-非男性-未婚；语义区别很容易甄别；其他词汇比如boy、girl、child也可以这样划分语义层次或类别；这样通过语义类别的不同或相同，词汇语义内涵与外延特征很容易甄别。
