Supplied materials

  • Paper or a browser scratch area; no audio recording, account or private information is needed.
  • Use the regular ar preterite for the stated speaker. Original sentence: “yo ___”. Infinitive: hablar (speak); time/context: one explicitly completed event yesterday. Choose only the missing verb. Candidate answers: (A) hablamos (B) hablaste (C) hablé (D) habló.
  • Use the regular ar preterite for the stated speaker. Original sentence: “tú ___”. Infinitive: estudiar (study); time/context: one explicitly completed event yesterday. Choose only the missing verb. Candidate answers: (A) estudiamos (B) estudiaste (C) estudié (D) estudió.

Learn the idea

The preterite presents a supplied past event as bounded or completed in the narrative. Forms depend on conjugation class and subject; time words help interpret the story but do not mechanically force one tense in every context. The practiced regular ar preterite endings are é, aste, ó, amos and aron. Their written accents distinguish stressed forms such as hablé and habló; the subject and intended completed-past context determine the needed form.

Remove ar and add the supplied subject’s preterite ending. In a completed yesterday event, yo hablé and ella habló refer to different speakers. Nosotros hablamos can share its spelling with the present, so interpretation needs context.

Ayer alone is not a universal tense switch; descriptions about yesterday can use other past forms. These prompts explicitly request a bounded completed event. Keep the accent rather than assume an unaccented look-alike expresses the same grammatical form.

  1. Copy the supplied example and underline its speaker, noun, time cue or evidence words.
  2. Apply the shown language rule; keep any required ending, accent or paired punctuation.
  3. Solve the changed independent check, then explain why one offered alternative fails.
  4. Complete all three new practice cases and use the model to correct the precise word or meaning.
Worked example

See the method in action

Supplied case: Use the regular ar preterite for the stated speaker. Original sentence: “yo ___”. Infinitive: hablar (speak); time/context: one explicitly completed event yesterday. Choose only the missing verb. Candidate answers: (A) hablamos (B) hablaste (C) hablé (D) habló. Solution: The supplied subject yo needs the é ending in this regular ar preterite pattern. Remove ar from hablar, leaving habl, then add é: hablé. The other offered forms belong to different subjects. Final result: hablé. Ayer alone is not a universal tense switch; descriptions about yesterday can use other past forms. These prompts explicitly request a bounded completed event. Keep the accent rather than assume an unaccented look-alike expresses the same grammatical form.

See the answer and explanation

estudiaste

The supplied subject tú needs the aste ending in this regular ar preterite pattern. Remove ar from estudiar, leaving estudi, then add aste: estudiaste. The other offered forms belong to different subjects.

Take it further

A third-person label says “ella miró”. Convert it to the person speaking about themself, yo, preserving mirar (look) and the regular ar preterite, context one explicitly completed event yesterday. Which replacement verb is needed? Candidate answers: (A) miramos (B) miraste (C) miré (D) miró. Expected result: miré. The supplied subject yo needs the é ending in this regular ar preterite pattern. Remove ar from mirar, leaving mir, then add é: miré. The other offered forms belong to different subjects.
