Answer:
The answer: "departing" (Example sentence: She is departing.)
Step-by-step explanation:
Present participle- this is a form of a verb that uses ing. It is used to show the Present Continuous Tense. This tense is also known as the "Present Progressive Tense" and it means that an ongoing action is actually happening right now. It could also mean that the action can take place in the future.
For example:
I am eating my lunch.
She is cooking in the kitchen.
The present participle is preceded by an auxiliary verb (BE verb). In the example above, these are "am" and "is." These are helpful in forming the tenses.
In the sentence "She is departing." The auxiliary verb here "is" while the present participle verb is "departing."
