I was giving a question by my teacher:

In a short answer, explain how subcatergorization accounts for the ungrammaticality of the following.

*The instructor suggested the students to study.
*The customer requested for a fork
*After getting home they devoured.

My text book does not go deep in depth about sub-catergorization. However, from what I understood. These sentences are ungrammatical because they make no sense. These words can not occur together in a sentence.


I am not really grasping the meaning of C-selection/sub-categorization.If you can suggest a website that explains it in simple terms. Or point me in the right direction...that would be helpful.

Please, any help is appreciated.
