  • Use the regular ar present for the stated speaker. Original sentence: “tú ___”. Infinitive: estudiar (study); time/context: today. Choose only the missing verb. Candidate answers: (A) estudia (B) estudiamos (C) estudias (D) estudio.

Learn the idea

Regular present endings connect a verb’s stem with its subject. These supplied actions occur now or habitually; a statement’s negative form keeps that agreement while changing its claim. For the five practiced subjects, regular ar present endings are o, as, a, amos and an. Remove ar from the infinitive, keep the stem, and add the ending matching the speaker.

Use the exact supplied subject before selecting an ending. Hablar becomes habl-o for yo and habl-amos for nosotros. Subject pronouns may be omitted in real discourse, but these tasks supply them explicitly so the intended form is clear.

Do not keep ar when a finite present verb is requested. A form can be a valid Spanish verb for another subject and still be wrong for this sentence. Irregular verbs require separate patterns; this lesson uses only the stated regular verbs.

  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.

Supplied case: Use the regular ar present for the stated speaker. Original sentence: “yo ___”. Infinitive: hablar (speak); time/context: today. Choose only the missing verb. Candidate answers: (A) habla (B) hablamos (C) hablas (D) hablo. Solution: The supplied subject yo needs the o ending in this regular ar present pattern. Remove ar from hablar, leaving habl, then add o: hablo. The other offered forms belong to different subjects. Final result: hablo. Do not keep ar when a finite present verb is requested. A form can be a valid Spanish verb for another subject and still be wrong for this sentence. Irregular verbs require separate patterns; this lesson uses only the stated regular verbs.
