  1. Conjugating stem changers in the preterite tense

  2. Stem changing infinitives Stem changing infinitives are named for what they do– change in the stem. You are going to make some alteration of the stem before adding the verb endings. You will use the preterite endings you already know. The hardest part of stem changers is knowing which ones change and which ones don’t.

  3. Two Rules for identifying Preterite Stem-Changers: 1. The infinitive mustbe a stem-changer in the presenttense. 2. The infinitive must end in –ir.

  4. Stem changers There are 2 different ways a stem changing infinitive can change (2 categories). -The first is ou. -This includes present tense oue.

  5. dormir = to sleep This is a stem changer in the preterite (because it is also a stem changer in the present tense). First separate the stem from the infinitive ending. Dorm- is the stem. Make the stem change ou New stem durm- Put into box– In the present tense, it looks like a boot. In the preterite tense, it looks like a sandal. Only the 3rd and 6th boxes (3rd person singular and 3rd person plural) make the stem changes.

  6. dormir = to sleep

  7. Stem changers The second category is ei. (This includes present tense changes eie and ei). preferir = to prefer is a stem changer in the preterite (because it is also a stem changer in the present tense). We use the same steps as for dormir. *When there is more than one vowel that could possibly make the change, choose the vowel closest to the –IR ending.

  8. Preferir = to prefer First separate the stem from the infinitive ending. prefer- is the stem. Make the stem change ei New stem prefir- Put into box– remember it will look like a sandal in the preterite. It will only change in the 3rd and 6th boxes.

  9. preferir = to prefer

  10. Stem changers . servir = to serve is a stem changer. It is the same steps as preferir.

  11. servir = to serve First separate the stem from the infinitive ending. serv- is the stem. Make the stem change ei New stem sirv- Put into box– remember it will look like a sandal. In the preterite, only the 3rd and 6th boxes show change.
