Semantic and syntax

Explanation:

The syntax is the study of rules and the principle f the language that determines the structure of the language. The syntax is the basic principle that defines the principle of combination of the linguistic symbols. Students and teachers are to be trained in the Chomsky syntax language.  

Semantic is related to the meaning of word, phrase, and discourse and the denotation and the senses of the language.  

Thus here in the above statement, Lisa's speech appeared to be intelligible but her vocabulary to appear restricted. she does not develop her semantic language. Thus she is not able to combine the sentences and understand the meaning of the sentence.
