- Usage in Finite Verb Phrases:
- In some finite verb phrases, the base form can function as the main verb, particularly in non-finite clauses.
- Example:
- “She asked him to leave.” (Here, “leave” is the base form and functions as the main verb in the non-finite clause.)

- Formation of Gerunds and Participles:
- Gerunds, which function as nouns, are formed by adding “-ing” to the base form.
- Present participles, used in progressive tenses, are also formed by adding “-ing” to the base form.
