1. Write the ellos/ellas form of 'traer' in the preterite tense.

Explanation

In Spanish, the verb "traer" means "to bring." In the preterite tense, which is used to describe actions completed in the past, the ellos/ellas form of "traer" is "trajeron." This form is derived from the irregular preterite conjugation of "traer," where the root changes to "traj-" and the appropriate endings for the third-person plural are added. Thus, "trajeron" indicates that a group of people brought something at a specific point in the past.

2. Apply the -zar rule: Write the yo form of 'empezar' in the preterite tense.

Explanation

In the preterite tense, the verb "empezar" undergoes a spelling change in the first person singular (yo) form to maintain the correct pronunciation. The -zar ending changes to -cé to preserve the soft "c" sound before the "e." Therefore, the yo form of "empezar" in the preterite tense is "empecé." This change is necessary to adhere to the rules of Spanish orthography, ensuring clarity in pronunciation.

Submit

3. Apply the -gar rule: Write the yo form of 'llegar' in the preterite tense.

Explanation

In Spanish, verbs that end in -gar undergo a spelling change in the preterite tense to maintain the correct pronunciation. For the verb "llegar," the yo form in the preterite is "llegué." The "g" changes to "gu" before the "é" to ensure the hard "g" sound is preserved. This adjustment is necessary because without it, the pronunciation would shift, leading to confusion. Thus, "llegar" becomes "llegué" in the first person singular form of the preterite tense.

Submit

4. Apply the -car rule: Write the yo form of 'buscar' in the preterite tense.

Explanation

In the preterite tense, the verb 'buscar' undergoes a spelling change in the first person singular (yo) form to maintain the correct pronunciation. The -car ending requires a change from 'c' to 'qu' before the 'é' to preserve the hard 'k' sound. Therefore, the yo form of 'buscar' in the preterite tense is 'busqué', reflecting this adjustment while indicating a completed action in the past.

Submit

5. Write the ellos/ellas form of 'leer' in the preterite tense. (spelling change verb)

Explanation

In the preterite tense, the verb 'leer' undergoes a spelling change in the third person plural form (ellos/ellas) to maintain the correct pronunciation. Instead of following the regular conjugation pattern for -er verbs, 'leer' changes to 'leyeron' to reflect the 'i' sound in the stem. This adjustment is necessary because, in the preterite, the 'i' would otherwise be silent if combined with the regular ending. Thus, 'leyeron' is the appropriate form for ellos/ellas when expressing that they read in the past.

Submit

6. Write the él/ella form of 'sentir' in the preterite tense. (stem-changing verb)

Explanation

In the preterite tense, the verb 'sentir' undergoes a stem change from 'e' to 'i' in the él/ella form. This alteration occurs because 'sentir' is a stem-changing verb that affects its conjugation in specific tenses. For the él/ella form, the correct conjugation is 'sintió', which reflects both the stem change and the appropriate ending for the third-person singular in the preterite tense. Thus, 'sintió' indicates that he or she felt something in the past.

Submit

7. Write the nosotros form of 'poder' in the preterite tense.

Explanation

In Spanish, the verb "poder" means "to be able to." In the preterite tense, which describes completed actions in the past, the nosotros form of "poder" is conjugated as "pudimos." This form indicates that "we were able to" or "we could" do something at a specific time in the past, reflecting a definite action that has been completed.

Submit

8. Write the tú form of 'hacer' in the preterite tense.

Explanation

In Spanish, the verb 'hacer' means 'to do' or 'to make.' In the preterite tense, which is used to describe actions completed in the past, the tú form of 'hacer' is conjugated as 'hiciste.' This form specifically indicates that you (informally) completed the action of doing or making something at a specific point in the past. The conjugation follows the irregular pattern of 'hacer' in the preterite tense, where the stem changes to 'hic-' before adding the appropriate ending for the tú form.

Submit

9. Write the él/ella form of 'estar' in the preterite tense.

Explanation

In Spanish, the verb 'estar' means "to be." In the preterite tense, which is used to describe actions that were completed in the past, the él/ella form of 'estar' is conjugated as 'estuvo.' This form indicates that someone was in a specific state or location at a particular time in the past. The conjugation reflects the irregular nature of 'estar' in the preterite, distinguishing it from its present tense forms.

Submit

10. Write the yo form of 'venir' in the preterite tense.

Explanation

In Spanish, the verb "venir" means "to come." When conjugated in the preterite tense for the first person singular (yo), it transforms into "vine." This form indicates a completed action in the past, signifying that the speaker came at a specific time. The preterite tense is used to express actions that are viewed as completed, distinguishing it from the imperfect tense, which describes ongoing or habitual actions in the past. Thus, "vine" effectively communicates that the action of coming has been fully accomplished.

Submit

11. Write the yo form of 'conducir' in the preterite tense.

Explanation

In Spanish, the verb 'conducir' means 'to drive.' In the preterite tense, the yo form is 'conduje,' which is used to indicate that the action of driving was completed in the past. This form is derived from an irregular conjugation pattern, where the root changes to 'conduj-' before adding the preterite ending '-e' for the first-person singular. Thus, 'conduje' specifically conveys that the speaker drove at some point in the past.

Submit

12. Write the tú form of 'saber' in the preterite tense.

Explanation

In Spanish, the verb 'saber' means "to know." In the preterite tense, which describes actions completed in the past, the tú form of 'saber' is conjugated as 'supiste.' This form indicates that the action of knowing occurred at a specific point in the past, making it distinct from other tenses that express ongoing or habitual actions. The preterite is commonly used for events that are viewed as completed.

Submit

13. Write the nosotros form of 'poner' in the preterite tense.

Explanation

In Spanish, the verb "poner" means "to put." In the preterite tense, which is used to describe actions completed in the past, the nosotros form of "poner" is conjugated as "pusimos." This form indicates that "we put" something at a specific point in the past. The preterite tense is characterized by its use of specific endings, and for "poner," the irregular stem "pus-" is combined with the appropriate ending for the nosotros form, which is "-imos."

Submit

14. Write the yo form of 'dar' in the preterite tense.

Explanation

In Spanish, the verb "dar" means "to give." In the preterite tense, which is used to describe actions completed in the past, the first-person singular form (yo) is "di." This form is irregular, deviating from the regular conjugation patterns typically seen in other verbs. Understanding this conjugation is essential for expressing past actions involving giving in a clear and accurate manner.

Submit

15. Write the ustedes form of 'tener' in the preterite tense.

Explanation

In Spanish, the verb "tener" means "to have." In the preterite tense, it is used to describe actions completed in the past. The "ustedes" form is used for addressing a group formally or informally in Latin America. The preterite conjugation for "ustedes" is "tuvieron," indicating that the group had something at a specific point in the past. This form is essential for expressing past actions involving multiple people.

Submit

16. Write the yo form of 'decir' in the preterite tense.

Explanation

In Spanish, the verb 'decir' means "to say" or "to tell." In the preterite tense, which is used for actions completed in the past, the first-person singular form (yo) of 'decir' is 'dije.' This form is irregular, as it does not follow the typical conjugation patterns for regular -ir verbs. Understanding this irregularity is crucial for accurate communication in past contexts.

Submit

17. Write the él/ella form of 'querer' in the preterite tense.

Explanation

In Spanish, the verb 'querer' means 'to want.' In the preterite tense, which is used to describe actions completed in the past, the él/ella form of 'querer' is conjugated as 'quiso.' This form indicates that he or she wanted something at a specific moment in the past. The preterite tense is characterized by its distinct conjugation patterns, and 'quiso' reflects the irregularity of this particular verb in the preterite form.

Submit

18. Write the tú form of 'ser' in the preterite tense.

Explanation

In Spanish, the verb "ser" means "to be." In the preterite tense, which is used to describe actions completed in the past, the second person singular form (tú) of "ser" is "fuiste." This form indicates that the subject, addressed informally as "tú," was something or someone at a specific point in time. The preterite tense emphasizes the completed nature of the action, distinguishing it from the imperfect tense, which describes ongoing or habitual actions in the past.

Submit

19. Write the nosotros form of 'ir' in the preterite tense.

Explanation

In Spanish, the verb "ir" means "to go." In the preterite tense, which indicates a completed action in the past, the nosotros form of "ir" is "fuimos." This form is derived from the irregular conjugation pattern of "ir" in the preterite, where it changes from its infinitive form to "fui" for the first-person singular and "fuimos" for the first-person plural. Thus, when referring to "we went," "fuimos" is the appropriate conjugation.

Submit

20. Write the ellos/ellas form of 'haber' in the preterite tense.

Explanation

In Spanish, the verb 'haber' is used as an auxiliary verb and can also indicate existence. In the preterite tense, the ellos/ellas form is 'hubieron.' This form is used to describe completed actions that occurred in the past. It is important to note that 'hubieron' is specifically used in plural contexts, aligning with the subject pronouns ellos or ellas, which refer to groups of people or things.
