Present Progressive.

The present progressive tense combines the present indicative of the verb estar (to be) with the present participle of another verb to indicate an action in progress. The present progressive tells what a person "is doing" right now.

• I am speaking with my mother right now.
• The children are playing in the yard right now. 
• Are you going to the store now?

The present participle never changes according to the tense. The progressive tense can be used in any time reference simply by changing the tense of estar, creating the present progressive, preterite progressive, the imperfect progressive, the future progressive, etc. This article explains how to form and when to use the present progressive tense.

Present Progressive Forms

The present progressive is a verb phrase consisting of both estar (the "is" part which indicates the tense) and the present participle (the "-ing" part which indicates what the action is). To form the present progressive, conjugate estar to the present indicative tense and add the present participle form of the verb that the person is actually doing.

Present Progressive Formula: estar + present participle (verb stem + -ando for -ar verbs/-iendo for -er and -ir verbs)

I am speaking                           We are speaking

You are speaking                     You (all) are speaking

You (formal) are speaking       You (all, formal) are speaking

He/she is speaking                   They are speaking

Single Current Actions

Simply, what a person is doing right now, and action they are currently participating in.
