Hi, Please tell me the answers to these.

1. Can a complement, whether it be an adjective, noun, or verb complement, work only with certain verbs and not all verbs? Yes, then why is that?

2. What is the functional terms for the underlined infinitive parts? What are they doing in the sentence?

He was permitted to play one game after the supper.

He felt inclined to argue with his brother.
Hi, Anon,

I should probably keep out of this. I don't think they used the expression "complement" when I was in school. The type of action the verb describes often limits its function.

Transitive verbs take objects. "She hit him."

Intransitive verbs don't. "She matured."

Some verbs can be both. "She studied." (intransitive)

"She studied hard." (intransistive with adverb modifying verb)

"She studied until midnight." (intransitive with prepositional phrase modifying verb)

"She studied algebra." (transitive, with object of the verb)

"Verbs of being" "She is a model." (predicate nominative)

"She is beautiful." (predicate adjective)

Active "I permitted him to play." (infinitive is object of the verb, "him" is indirect object)

Passive "He was permitted to play" ("He" becomes the subject; the infinitive is still the direct object)

Intransitive "I felt sick to my stomach." ("sick" is an adverb modifying the intransitive verb "felt" ; the infinitive is an adverbial phrase modifying the adverb "sick")

"He felt inclined to argue with his brother." (ditto, plus a prepositional phrase modifying the infinitive)
Wow! I just read this again. I really messed up. Sorry. Guess my brains were out to lunch.

"to my stomach" is a prepositional phrase, not an infinitive. I know you're sharp enough to spot that. It still functions as an adverbial phrase, which it must be by definition to modify another adverb. (I guess what I call "modifiers" are what you call "compliments.")
