Here's a breakdown:
Components of a complete infinitive phrase:
* Infinitive: The base form of the verb preceded by "to" (e.g., to run, to sing, to eat).
* Object: The noun or pronoun that receives the action of the verb (e.g., to read a book, to help her).
* Modifiers: Adjectives or adverbs that describe the infinitive or its object (e.g., to quickly run, to read a fascinating book).
* Complements: Words that complete the meaning of the verb (e.g., to be happy, to feel tired).
Functions of a complete infinitive phrase:
* Noun: The phrase acts as the subject or object of the sentence.
* Adjective: The phrase modifies a noun or pronoun.
* Adverb: The phrase modifies a verb, adjective, or another adverb.
Examples:
Noun:
* To travel the world is my dream. (Subject of the sentence)
* I want to learn a new language. (Object of the verb "want")
Adjective:
* He had the courage to speak out. (Modifies the noun "courage")
* She's the one to ask. (Modifies the pronoun "one")
Adverb:
* I went to the store to buy milk. (Modifies the verb "went")
* He was too tired to study. (Modifies the adjective "tired")
Key Point: A complete infinitive phrase always includes the infinitive form of the verb "to + verb." It's important to identify the entire phrase and its role in the sentence to understand its meaning and function.
