What do you to a word when put it in present perfect progressive tense?

To put a word in the present perfect progressive tense, you need to do the following:

1. Identify the base form of the verb: This is the infinitive form of the verb without "to" (e.g., walk, eat, play).

2. Add "-ing" to the base form: This creates the present participle (e.g., walking, eating, playing).

3. Use the auxiliary verb "have" or "has" depending on the subject (singular or plural).

4. Add "been" after the auxiliary verb: This completes the present perfect aspect.

Here's an example:

* Base verb: "play"

* Present participle: "playing"

* Auxiliary verb: "have" (for plural subjects) or "has" (for singular subjects)

* Present perfect progressive: "have/has been playing"

Putting it together:

* I have been playing video games all day.

* She has been playing the piano since she was a child.

* We have been playing soccer in the park.

Remember: The present perfect progressive tense describes an action that started in the past and is still continuing in the present.
