What are you doing right now?  You're reading this Spanish lesson, of course.  In this lesson you'll learn how to make the -ing form of verbs, in Spanish.  You 'll also learn the official name of the -ing form: the present participle.

Steps:
1. Take off the verb ending (-ar, -er, -ir)
2. Add an ending:
  •  -ar verbs: add -ando
  •  -er and -ir verbs: add -iendo


Examples:
   hablar (talk) - ar =   habl + ando =   hablando (talking)
   comer (eat) - er =  com + iendo =  comiendo (eating)
   vivir (live) - ir =  viv + iendo =  viviendo (living)
 

Stem-changing:
Some verbs stem change in the present participle:
  • only -ir verbs, and only the -ir verbs that stem change in the present tense
  • in the present participle, they'll only stem change by 1 vowel:  e-i or o-u

Here are some common stem-changing verbs:
 dormir
 sleep

  durmiendo
 sleeping
 morir
 die

  muriendo
 dying
 vestir
 dress

  vistiendo
 dressing
 decir       
 say

  diciendo
 saying
 pedir
 ask for

  pidiendo
 asking for
 sonreír 
 smile

  sonriendo
 smiling
 seguir 
 follow 

  siguiendo
 following
 
 
Changing i to y:
If when you make the present participle, you end up with 3 vowels in a row, you'll need to make a spelling change. That's because of a Spanish grammar rule:

    Rule: only 2 vowels in a row (silent u can be a 3rd)

In these verbs, you'll change the letter i to y. Why? Y and i make the same sound, but y isn't a vowel.  
Here are some of these verbs:
 oír
 hear

  oyendo
 hearing
 leer
 read

  leyendo 
 reading
 construir
 build

  construyendo 
 building
 caer
 fall

  cayendo
 falling
 traer
 bring
  trayendo
 bringing
