Infinitive
An infinitive is the base form of a verb, often preceded by the word "to." It can express actions, states, or conditions without indicating a specific subject or tense. For example, in the phrase "to run," "run" is the infinitive form of the verb. Infinitives can function as nouns, adjectives, or adverbs in a sentence.
Infinitives can also appear in different forms, such as the "bare infinitive," which omits "to," as in "I can swim." Additionally, infinitives can be used in phrases like infinitive phrases, which include the infinitive and its modifiers or complements, such as "to eat quickly."
