Here's the breakdown:
* Infinitive: The basic form of a verb, often preceded by "to". For example, "to run", "to eat", "to sleep".
* Bare infinitive: The basic form of a verb without the "to". For example, "run", "eat", "sleep".
"To run" is an infinitive, while "run" is a bare infinitive.
Examples:
* Infinitive: "I want to run a marathon."
* Bare infinitive: "I will run a marathon."
Why the confusion?
The terms "infinitive" and "bare infinitive" are sometimes used interchangeably, leading to confusion. It's important to remember that the "to" is part of the infinitive form, while the bare infinitive is simply the verb without the "to".
