Why is this versatility so important?
* Clarity and Conciseness: Infinitives can express actions or states of being in a compact and clear way.
* Flexibility: They can be used in various sentence structures and grammatical functions, allowing for diverse expression.
* Sophisticated Language: Mastering the use of infinitives can add a layer of sophistication to your writing and speaking.
Key Points to Remember:
* Infinitives are typically formed with "to" followed by the base form of the verb (e.g., to run, to eat).
* Sometimes, the "to" is omitted in certain cases, particularly after modal verbs (e.g., I *can* swim, I *should* leave).
