What is an infinitive?

An infinitive is a verb form that we often use when we refer to a verb, as well as when it's serving as a complement. An infinitive always starts with the word "to."

to walk
to see
to give
to be loved (passive form)
etc.

An infinitive is a grammatical term used to describe the base form of a verb or the "to" form of a verb. In English, infinitives are formed by adding the word "to" before the base form of the verb, such as "to go," "to eat," or "to speak."

To understand the concept of an infinitive, you can follow these steps:

Step 1: Identify the verb in the sentence.
Look for the action word in the sentence. For example, in the sentence "I want to eat ice cream," the verb is "eat."

Step 2: Check if the verb is in its base form or "to" form.
If the verb is in its base form or the "to" form, then it is an infinitive. For example, in the sentence "I want to eat ice cream," the verb "eat" is preceded by the word "to," making it an infinitive.

Step 3: Understand the function of the infinitive.
Infinitives can function as nouns, adjectives, or adverbs in a sentence. For example, in the sentence "To travel is my passion," the infinitive "to travel" functions as the subject of the sentence.

In summary, an infinitive is the base form of a verb or the form that begins with "to." It is used in various ways in a sentence, depending on its function.
