<p>I’m not sure I understand what you mean…
Neither “stating” or “to state” is acting as an adjective modifying the noun. </p>
<p>“Stating” is the continuous participle of “state” and it applies the the noun before “rules”, not “rules”.
(ex) YOU are stating rules.–> “You” is the subject, “are” is the helping verb, “stating” is the verb, and “rules” is the OBJECT of the sentence. It is recieving the action of being stated, but without any change in qualities. “Rules” still just means “rules”.</p>
<p>“To state” is the infinitive form of the state, and usually, infinitive forms of verbs are used to demonstrate a purpose or to list in sequence. It is usually used after another verb, or following the object of the sentence.
(ex) I do homework (to get) good grades, (to learn) more, and (to go) to a good college.</p>
<p>“Rules to state” is a phrase, and “to state” is not describing “rules”, but WHY the “rules” are there.
(ex) SHE made the rules to state what is prohibited.–> “She” is the subject, “made” is the verb, “the rules” is the object, “to state” explains WHY she made “the rules”. There is still no change in the condition of “rules” (by change, I mean, you don’t know if the rules are bad, good, strict, etc.).</p>
<p>The only way I see how “state” could be used as an adjective is if “rules” was the SUBJECT and not the OBJECT of the sentence, followed by a form of “to be”.
(ex) The rules are being stated.–> “The rules” is the subject, “are” is the helping verb, “Being” is the main verb, and “stated” is decribing rules. It’s acting as an adjective because “rules” are not just “rules”, but they are “stated rules”. The difference is subtle, but it matters.</p>
<p>I’m so sorry if you find this all really confusing! >__<;</p>
