A Question about Present Progressive

Question

Just a simple question about "Present Progressive". On a website, it says -

To form the present participle of -ir stem changing verbs, change e->i and o->u in the stem, and then add -iendo to the stem of the verb.

servir: sirviendo e->i pedir: pidiendo e->i decir: diciendo e->i

dormir: durmiendo o->u morir: muriendo o->u poder: pudiendo o->u

Does it mean if the verb contains the letters "e" and "o" near the first consonant we have to change it into "i" or "u" in the present tense? Like VIVIR, the vowel "i" follows the "v", thus there is no need to make any change,i.e. viviendo. (It is more like an intuition,actually.)

What do you think?

Remember that these types of changes only occour in -IR verbs. There are other verbs that change in the preogressive in different ways, but the e>I and o>u are only in IR verbs - BradyLabuda, Jun 29, 2012

Answer 1

mostly all -IR verbs change with those rules...

divertirse--> divirtiéndose

seguir-->siguiendo

No change in Vivir since there is no "e" or "o" to change.

After a while when you say them enought times, you'll realize "hmm...that just doesnt sound right..." and then these changes should come naturally.

Deciendo......doesn't sound right.

Diciendo.......better.

Good question.

No, no changes are necessary.

Tutear = Tuteando

Mirar = Mirando
