The present progressive
The present progressive is a tense that is used to describe ‘what you ARE DOING’. It is often referred to as an action in progress.
Formation
To form the present progressive you need the following:
Estar + present participle (gerund)
‘Estar’ will agree with the person that is doing the action.
For example:
Yo estoy tomando un examen. – I am taking a test.
Nosotros estamos comiendo la cena. – We are eating dinner.
Forming the present participle
a. Regular Verbs
To form the present participle, start with the infinitive, remove the -AR, -ER, or -IR, and add the respective endings below.
-AR
ex. Hablar habl- + ANDO –> hablando
-ER
ex. Beber beb- + IENDO –> bebiendo
-IR
ex. Asistir asis- + IENDO –> asistiendo
b. Irregular Verbs
1. Stem-changing –IR verbs
Verbs that are stem-changing in the present tense and end in -IR can undergo two possible changes when forming the present participle. They will change from:
E –> I
or
O –>U
For example:
Decir –> diciendo
Dormir –> durmiendo
Mentir -> mintiendo
Morir –> muriendo
Pedir –> pidiendo
Sentir –> sintiendo
2. -ER and -IR verbs that have a stem that ends in a vowel, utilize a ‘Y’ when forming the present participle instead of an ‘I’.
For example:
Construir
constru- +YENDO –> construyendo
Leer
le- +YENDO –> leyendo
Oír
o- +YENDO –> oyendo
Traer
tra- + YENDO –> trayendo
