1. Forming Spanish Present Participles (-ing words) to use in the Present Progressive Tense

2. Regular Verbs Take the last two letters off the verb infinitive:
Hablar (to speak) = habl
Comer (to eat) = com
Escribir (to write) = escrib
For –ar verbs add –ando
habl+ando = speaking
For –er and –ir verbs add -iendo
com+iendo = eating, escrib+iendo = writing

3. When a verb stem ends in a vowel:
For –er and –ir verbs, once you have removed the last two letters, if the stem ends in a vowel add –yendo instead of –iendo. Atraer = atra + yendo = atrayendo (attracting) Caer = ca + yendo = cayendo (falling) Construir = constru + yendo = construyendo (building) Whenever an unstressed i appears between two vowels use the- yendo ending instead of the –iendo ending.

4. The present participle of IR (to go) is a special case
If you remove the –ir ending of IR you have nothing left,
so just go ahead and add yendo.
The present participle of IR is yendo (going).

5. Change to the stem!
Some verbs also change in the stem when forming the present participle. When an –ir verb has a stem change in the third person preterite (e>i or o>u) it will have the same change in its present participle form. Decir (to say) = dijo (he said) = diciendo (saying) Hervir (to boil) = hirvió (it boiled) = herviendo (boiling) Pedir (to ask for) = pido (he asked for) = pidiendo (asking for) Venir (to come) = vino (he came) = viniendo (coming) Dormir (to sleep) = durmió (he slept) = durmiendo (sleeping)

6. Want to apply what you’ve learnt?
These verbs all have stems that end in a vowel:
Creer – to believe
Leer – to read
Traer – to bring
Contribuir – to contribute
Huir – to flee, to run away
Influir – to influence
So what which ending will they use for their present participle?
-iendo, -ando, -endo or -yendo?
You’ve got it! - YENDO

7. -Yendo Endings
Creer – to believe Creyendo = believing Leer – to read Leyendo = reading Traer – to bring Trayendo = bringing Contribuir – to contribute Contribuyendo = contributing Huir – to flee, to run away Huyendo = fleeing, running away Influir – to influence Influyendo = influencing

8. What’s the present participle for IR (to go)?
Yup, you guessed it! YENDO = going

9. And what happens when the verb stem of an –er or –ir verb ends in ll or an ñ?
Because those letters contain the sound of an i at the end you can just add –endo instead of –iendo. Engullir = to gulp, guzzle, devour, wolf down Engullendo = gulping, guzzling, devouring, wolfing down

10. And finally for those verbs that change in the stem for their third person preterite form?
Just remember to keep the stem change for the present participle as well!
Competir (to compete) = compitió (he competed) = compitiendo (competing)
Conseguir (to get) = consiguió (he got) = consiguiendo (getting)
Morir (to die) = murió (he died) = muriendo (dying)

11. So that should pretty much keep you covered for forming any present participle for any Spanish verb!
So what are you waiting for?
Off you go and speak some Spanish!
