Answer:
Verbal: to eat
Type of Verbal: Infinitive
Function of Verbal: Adverb
Step-by-step explanation:
Verbals are described as the non-finite verb forms that do not function as a verb in the sentence. They primarily function as nouns, adverbs, or adjectives in the sentence and remain unaffected by the change in the tense of the sentence.
In the given sentence, 'to eat' is the verbal infinitive as it consists of 'to + base form of the verb(eat).' It is functioning as an adverb in the sentence as it modifies the clause 'left the movie early' by providing details about it. It is the non-finite verb form that is neutral in respect to any inflection in the tense of the sentence.
