The noun infinitive can be a subjectThe subject tells who or what about the verb.  Source: Lesson 91, a direct objectA direct object receives the action performed by the subject.

, a predicate nominativeA predicate nominative or predicate noun completes a linking verb and renames the subject. It is a complement or completer because it completes the verb. Predicate nominatives complete only linking verbs. The verb in a sentence having a predicate nominative can always be replaced by the word equals.  Source: Lesson 102, an appositiveAn appositive is a word or group of words that identifies or renames the noun or pronoun that it follows. It is set off by commas unless closely tied to the word that it identifies or renames. ("Closely tied" means that it is needed to identify the word.) An appositive can follow any noun or pronoun.  Source: Lesson 128, or an object of a prepositionA preposition is a word that begins a prepositional phrase and shows the relationship between its object and another word in the sentence. A preposition must always have an object.  Source: Lesson 180.

I like to eat. (direct object)
A fun thing is to eat. (predicate nominative)
