What is an infinitive?
An infinitive is the basic form of a verb, usually preceded by the word "to." Examples include: *to run*, *to eat*, *to sleep*, *to learn*, *to play*.
Types of infinitive sentences:
1. Infinitive as the subject:
* To err is human. (The infinitive "to err" is the subject of the sentence.)
* To travel is to experience new cultures. (The infinitive "to travel" is the subject, and the infinitive "to experience" is part of the predicate.)
2. Infinitive as the object:
* I love to sing. (The infinitive "to sing" is the object of the verb "love".)
* She wants to learn French. (The infinitive "to learn" is the object of the verb "wants".)
3. Infinitive as part of a prepositional phrase:
* She is excited about going to the concert. (The infinitive "going" is part of the prepositional phrase "about going.")
* We're looking forward to seeing you. (The infinitive "seeing" is part of the prepositional phrase "forward to seeing".)
4. Infinitive as part of a noun clause:
* I don't know what to do. (The infinitive "to do" is part of the noun clause "what to do," which functions as the object of the verb "know".)
Examples of infinitive sentences:
* To be or not to be, that is the question. (Subject)
* I want to go to the beach. (Object)
* He's looking forward to graduating. (Prepositional phrase)
* My biggest dream is to travel the world. (Noun clause)
* It's time to start working on that project. (Adverbial)
Remember: Infinitives can be used in a variety of ways in a sentence. They add flexibility and expressiveness to your writing.
