Types of Infinitives

Infinitives come in two forms:

1. Full Infinitive
   This is the most common form, combining "to" with the base verb.
   Use: Commonly used after certain verbs, adjectives, or to show purpose
   Example: He loves to swim.
   
2. Bare Infinitive
   This form uses only the base verb, typically after modal verbs or "let" and "make."
   Use: Typically follows modal verbs (e.g., can, should), causative verbs (e.g., make, let), or verbs of perception (e.g., see, hear).
   Example: She can run fast.
