02 Preterite – IR Stem-changers (e-i)

Posted by Señor Jordan on Feb 8, 2009 in conjugation, grammar, ir, preterite, reflexives, stem-changers, verbs, year 2 |

Hola. Finally there is a video (although a little long) to explain those strange stem-changers in the preterite.  Although you might remember that -ar and -er verbs in the preterite don’t stem-change like they do in the present, the -ir verbs have to be weird.  This video will explain how (e-ie) and (e-i) -ir verbs work in the preterite.  Enjoy!

Notice that servir is actually an (e-i) verb in the present. This was a mistake in the video!

Let me know if you have any questions, comments or suggestions about this video below!

Cuando ha un momento, puede hacer otro video de verbo de haber, el presente y el preterito, por favor.

Necesito entender el verbo haber y el verbo tener.

Por ejemplo

I have been studing spanish for three months. Tengo will not be used but he will be used, why?

According to this video(4:46) “servir” changes from e to ie, but I think it is from e to i.
Great videos thank you.

Thank you for your excellent videos. I am using them for review and am viewing them in sequence. This, the 113th one, has the most difficult material so far. I’ll have to gather strength before viewing again.
