Types of Infinitives
Full Infinitive (To-Infinitive): This is the most common type and consists of the word "to" followed by the base form of the verb.
- Examples: to run, to eat, to think, to be
-
Bare Infinitive: This is the base form of the verb without "to". It is used after modal verbs (such as can, will, should, must) and certain other verbs (such as let, make, help).
- Examples: run, eat, think, be
In addition to these two main types, there are also some other forms of infinitives:
* 3. Split Infinitive: This occurs when an adverb or other word is placed between "to" and the base verb in a full infinitive.
-
- Example: to boldly go (from Star Trek)
- While split infinitives were traditionally frowned upon, they are now generally accepted in modern English.
-
4. Perfect Infinitive: This form is used to express an action that was completed before the time of the main verb. It is formed using "to have" + past participle.
- Example: to have finished
-
5. Continuous Infinitive: This form is used to express an ongoing or incomplete action. It is formed using "to be" + present participle (-ing form).
- Example: to be running
-
6. Passive Infinitive: This form is used to express an action being done to the subject. It is formed using "to be" + past participle.
- Example: to be seen
