Supplied materials

  • Paper or a browser scratch area; no audio recording, account or private information is needed.
  • Use the regular ar imperfect for the stated speaker. Original sentence: “yo ___”. Infinitive: hablar (speak); time/context: an explicitly repeated past habit. Choose only the missing verb. Candidate answers: (A) hablaba (B) hablaban (C) hablabas (D) hablábamos.
  • Use the regular ar imperfect for the stated speaker. Original sentence: “tú ___”. Infinitive: estudiar (study); time/context: an explicitly repeated past habit. Choose only the missing verb. Candidate answers: (A) estudiaba (B) estudiaban (C) estudiabas (D) estudiábamos.

Learn the idea

The imperfect can present a past situation from inside its ongoing or repeated course rather than as one completed event. Compare the narrator’s intended viewpoint; do not replace this distinction with a claim that one tense means long and another short. Regular ar imperfect endings are aba, abas, aba, ábamos and aban for the practiced subjects. Yo and ella can share an aba form, while the subject or surrounding text clarifies who is involved.

Remove ar and add the requested subject ending. The supplied context explicitly describes a repeated past habit, so hablabas or estudiábamos presents that routine rather than counting one completed event. Preserve the accent in ábamos.

A form’s shared spelling does not mean every subject is interchangeable. These questions name the intended participant. Imperfect does not require a long duration; it expresses the supplied background/habit viewpoint rather than a universal clock-length rule.

  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 imperfect for the stated speaker. Original sentence: “yo ___”. Infinitive: hablar (speak); time/context: an explicitly repeated past habit. Choose only the missing verb. Candidate answers: (A) hablaba (B) hablaban (C) hablabas (D) hablábamos. Solution: The supplied subject yo needs the aba ending in this regular ar imperfect pattern. Remove ar from hablar, leaving habl, then add aba: hablaba. The other offered forms belong to different subjects. Final result: hablaba. A form’s shared spelling does not mean every subject is interchangeable. These questions name the intended participant. Imperfect does not require a long duration; it expresses the supplied background/habit viewpoint rather than a universal clock-length rule.

Helpful tips
  • Remove ar and add the requested subject ending.
  • A form’s shared spelling does not mean every subject is interchangeable.
Use the regular ar imperfect for the stated speaker. Original sentence: “tú ___”. Infinitive: estudiar (study); time/context: an explicitly repeated past habit. Choose only the missing verb.

See the answer and explanation

estudiabas

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

Take it further

A third-person label says “ella miraba”. Convert it to the person speaking about themself, yo, preserving mirar (look) and the regular ar imperfect, context an explicitly repeated past habit. Which replacement verb is needed? Candidate answers: (A) miraba (B) miraban (C) mirabas (D) mirábamos. Expected result: miraba. The supplied subject yo needs the aba ending in this regular ar imperfect pattern. Remove ar from mirar, leaving mir, then add aba: miraba. The other offered forms belong to different subjects.
