Understanding Preterite Stem Changing Verbs
In Spanish, stem-changing verbs are those verbs that undergo a vowel change in their stem when conjugated in certain tenses. The preterite tense features a unique set of stem-changing verbs, which typically only change in the third person singular and plural forms (él/ella/usted and ellos/ellas/ustedes).
Types of Stem Changes
There are several types of stem changes that can occur in the preterite tense:
1. e to i: These verbs change the vowel 'e' in the stem to 'i'.
- Example: pedir (to ask for) → él pidió
2. o to u: These verbs change the vowel 'o' in the stem to 'u'.
- Example: morir (to die) → él murió
3. e to ie: This type does not occur in the preterite tense as it does in the present tense, but verbs like sentir (to feel) have an e to i change.
- Example: sentir → él sintió
