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

句法结构，或LF，是由一个单一的生成系统和一个结构同态，它是由语义解释组成。每个词汇项（VI）都是一组（1）不可预测的语音信息，（2）不可预测的语义信息，以及与复杂句法结构相关联的规范。开放类维斯的标签，动词（V）/名词（N）/形容词（A），可以被认为是这种"插入环境"的变音符号。"由于LF和它的解释之间的同态，动词被解释为一个可能性的谓词，其参与者的规范和名词（根）被解释为一种实体的名称。V/N/A这三个词汇范畴的存在很可能源于人类在感知世界时关注和识别可能性/实体/和实体属性的先天概念倾向。

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.
