In English, there are two main types of infinitives: the "bare infinitive" and the "to-infinitive." The bare infinitive is the base form of the verb without "to" (e.g., "go," "see"), while the to-infinitive includes "to" followed by the base form of the verb (e.g., "to go," "to see"). Additionally, there are variations such as the split infinitive, where an adverb is placed between "to" and the verb (e.g., "to boldly go").
It is called the infinitive.
