Based on the examples provided and the hint about -CAR, -GAR, -ZAR verbs in the preterite tense, here's a general grammar rule that could explain the pattern:
**General Rule for -CAR, -GAR, -ZAR Verbs in the Preterite Tense:**
When conjugating verbs that end in -CAR, -GAR, and -ZAR in the preterite tense, a spelling change occurs in the "yo" form to maintain the original sound of the infinitive:
- **-CAR verbs:** The "c" changes to "qu" before the ending "-é".
- Example: tocar (to touch) → yo toqué
- **-GAR verbs:** The "g" changes to "gu" before the ending "-é".
- Example: llegar (to arrive) → yo llegué
- **-ZAR verbs:** The "z" changes to "c" before the ending "-é".
- Example: empezar (to begin) → yo empecé
**Testing the Rule with Example Sentences:**
1. **Tocar (to touch):**
- Infinitive: tocar
- Yo form in preterite: yo toqué (correct)
2. **Llegar (to arrive):**
- Infinitive: llegar
- Yo form in preterite: yo llegué (correct)
3. **Empezar (to begin):**
- Infinitive: empezar
- Yo form in preterite: yo empecé (correct)
This rule explains why the spelling changes occur in the preterite tense for -CAR, -GAR, and -ZAR verbs, ensuring clarity and consistency in pronunciation while maintaining grammatical correctness.
