Common Mistakes with Imperfect of Ir

Incorrect: Yo iría al cine todos los días. (using conditional) — I used to go to the cinema every day.

Correct: Yo iba al cine todos los días. — I used to go to the cinema every day.

For past habits, use imperfect (iba), not conditional (iría). Iría would mean I would go (hypothetical).

Incorrect: Iba al cine ayer. — I went to the cinema yesterday.

Correct: Fui al cine ayer. — I went to the cinema yesterday.

Ayer (yesterday) is bounded, a single completed event. Use preterite fui, not imperfect iba.

Incorrect: Ibamos juntos. (missing accent) — We used to go together.

Correct: Íbamos juntos. — We used to go together.

Nosotros form has an accent: íbamos. Without it, the spelling is wrong.

Iba A + Infinitive = Was Going To
