I recently encountered a sentence structure that has piqued my curiosity, and I'm hoping to get some insights from the community here. The structure involves the use of two verbs in a relative clause, where one seems to express perception or cognition and the other describes a state or action. Here are two examples that illustrate this:
"Focus on the design elements that you feel are most strongly represented in that particular work of art."
"Consider the books that you find are most engaging in the library."
I'm pretty sure that they are the right sentences without any grammatical errors since the former one is an excerpt from a TOEFL TPO.
In both examples, the relative clauses ("that you feel are most strongly represented" and "that you find are most engaging") include two verbs: a perception verb ("feel", "find") and another verb forming a passive voice or linking to an adjective ("are represented", "are engaging").
My questions are:
What is the grammatical term for this specific structure involving two verbs within a relative clause?
Is this construction common in English, and are there any rules or guidelines on how to correctly use it?
Thank you in advance!
