The Italian -ing form – present progressive
This verb form is used to express an action while it is still happening.
Io sto scrivendo una lettera – I am writing a letter.
As you can see from the example, we need to use the verb ‘stare’ followed by the gerund of the verb expressing the action.
The verb stare is conjugated like this:
io sto
tu stai
lui/lei sta
noi stiamo
voi state
loro stanno
Along with the appropriate conjugation of ‘stare’, you need the gerund of the verb you want to use (the gerund does not conjugate according to the subject of the verb – it’s always the same.)
