The "Present Progressive" is a compound verb structure made up of a conjugated form of estar (in present tense) and a present participle.
The purpose of the present progressive is to say what is happening at a specific moment in time.
We use the words "Ahora" (Now) and "Ya" (Already) frequently with the present progressive.
