Formation of Present Progressive Tense

Affirmative Form	Subject + am / is / are + Verb (ing) + Complement I am learning English right now.
Negative Form	Subject + am not / isn't / aren't + Verb (ing) + Complement I am not learning French right now.
Question Form	Am / is / are + Subject + Verb (ing) + Complement Is he going to work?
Negative Question	Am...not / isn't / aren't + Subject + Verb (ing) + Complement Am I not coming with you to the mall?

Verb (ing)

The most common state of the verb(ing) is just simply the verb itself + letters "ing"

walk - walking
talk - talking
turn - turning
learn - learning...

However, this rule does not always apply. See present progressive tense spelling rules for details.
