In Search of the Origins of the Lexical Syntactic Categories : a Comparative Study of Japanese and English

句法结构（LF）由单个生成系统生成，与之同态的结构由语义组合解释。每个词汇（VI）都是一束(1)不可预测的语音信息，(2)不可预测的语义（百科全书式）信息，以及与复杂句法结构的关联规范。开放类VIs的标签，动词(V)/名词(N)/形容词(A)，可以被认为是这种“插入环境”的变音符。由于LF及其解释之间的同态性，动词被解释为具有其参与者规范的可能性的谓词，名词（根）被解释为一种实体的名称。V/N/A这三种词汇类别的存在很可能源于人类在感知世界时关注和识别偶然性/实体/实体属性的固有概念倾向。

Syntactic structure, or LF, is generated by a single generative system and a structure homomorphic to it is interpreted compositionally by semantics. Each vocabulary item(VI) is a bundle of (1) unpredictable phonological information, (2) unpredictable semantic (encyclopedic) information, and specifications for its association with complex syntactic structures. The labels for open-class VIs, verb(V)/noun(N)/adjective(A), can be considered to be a diacritic for this "environment of insertion." Because of the homomorphism between the LF and its interpretation, a verb is interpreted to be a predicate of an eventuality with a specification of its participants and a noun (root) is interpreted to be the name of a kind of entity. The existence of three lexical categories, V/N/A, may very well originate from the innate human conceptual propensity to focus on and identify eventualities/entities/and properties of entities in perceiving the world.
