Here's what it means:
Progressive tense indicates an action or state that is ongoing or in progress at a specific point in time. It's formed by using the present participle of the main verb (the -ing form) with a form of the auxiliary verb "be".
Here are some examples:
* Present Progressive: I am eating breakfast. (The action of eating is happening now)
* Past Progressive: She was sleeping when the phone rang. (The action of sleeping was happening in the past)
* Future Progressive: They will be playing soccer tomorrow. (The action of playing will be happening in the future)
Key takeaways:
* Action in progress: The progressive tense emphasizes the continuous nature of the action.
* Specific time frame: It always indicates a specific time point in the past, present, or future.
* Not always about duration: Even though it often describes actions that last for a while, it can also indicate momentary actions.
So, "progressive verb" is a shortcut for referring to verbs used in the progressive tense, which describes ongoing actions.
