iba a + Infinitive
Past Ir a
'Iba a + infinitive' means 'was going to': plans may or may not be fulfilled. 'Fui a + infinitive' often means 'went to', but does not always require physical movement.
How It Works
1. Imperfect Aspect: Iba a + Infinitive
The imperfect form (imperfect of ir + a + infinitive) creates a 'past future' perspective. It expresses what someone was planning or about to do. It is often followed by an interruption, but non-fulfilment comes from context, not from iba a alone.
Examples:
• Iba a salir, pero empezó a llover. (I was going to go out, but it started raining.)
• ¿Qué ibas a decir? (What were you going to say?)
2. Preterite Aspect: Fui a + Infinitive
When using the preterite (preterite of ir + a + infinitive), a common use describes a trip or movement undertaken with a purpose. This does not prove that the intended action succeeded.
Examples:
• Fui a comprar pan. (I went to buy bread; the sentence does not itself guarantee that I bought it.)
3. Reported Speech Contexts
In reported speech, present plans using ir + a + infinitive shift naturally into the imperfect past form ('Voy a estudiar' becomes 'Dijo que iba a estudiar').
4. Contrast with Related Structures
While estar por / para + infinitive can indicate readiness, inclination, or something pending, depending on the preposition and context, 'iba a + infinitive' is broader, covering any scheduled or intended past action.
Preterite ir a can also describe an attempt or an unexpected development without a literal trip: Fue a decir algo, pero lo interrumpieron. (He started to say something, but they interrupted him.) Thus fui a llamarte is not inherently ungrammatical; it can have a different viewpoint from the background intention iba a llamarte.
Examples (4)
- Iba a llamarte anoche, pero se me apagó el teléfono.
I was going to call you last night, but my phone turned off.
Word by Word: I-was-going to to-call-you last-night, but self to-me turned-off the phone.
Uses 'iba a + infinitive' to express an unfulfilled intention in the past due to an interruption.
- Ayer fuimos a hablar con el director sobre el proyecto.
Yesterday we went to speak with the director about the project.
Word by Word: Yesterday we-went to to-speak with the director about the project.
Uses 'fui a + infinitive' (preterite) to express a completed trip made in order to execute an action.
- María me dijo que iba a llegar tarde por el tráfico.
María told me that she was going to arrive late because of traffic.
Word by Word: María to-me told that she-was-going to to-arrive late because-of the traffic.
Reported speech shifts the anticipated event expressed by voy a into a past viewpoint with iba a; arriving late need not be an intention.
- Íbamos a coger el tren de las cinco, pero perdimos el autobús.
We were going to catch the five o'clock train, but we missed the bus.
Word by Word: We-were-going to to-catch the train of the five, but we-lost the bus.
Shows 'íbamos a + infinitive' setting up an intended past plan that could not be executed.
Common Mistakes
Using 'fui a' when the intended viewpoint is a background plan.
Fui a llamarte, pero no tuve tiempo.Iba a llamarte, pero no tuve tiempo.For the ordinary background intention 'I was going to call you', use iba a. Fui a llamarte can be grammatical with a movement or attempted-action reading; it does not necessarily mean a completed physical trip. The contrast here concerns intended viewpoint.
Omitting the preposition 'a' between the conjugated verb 'ir' and the infinitive
Iba comprar el libro ayer.Iba a comprar el libro ayer.The structure ALWAYS requires the preposition 'a' after conjugated forms of 'ir' before an infinitive.
