acabar por + Infinitive

End Up Doing

Level 6

Use 'acabar por + infinitive' to say what someone 'ends up doing'.

How It Works

Acabar por + infinitive presents an action as the eventual outcome of a process: Acabé por aceptar (I ended up accepting). Conjugate acabar and keep the next verb in the infinitive.

The preceding events may involve hesitation, pressure, or an unexpected result, but deliberate choice is not required: Si sigues así, acabarás por perderlo (If you carry on like that, you will end up losing it).

Acabar + gerund and terminar por + infinitive can express a similar final outcome. Context supplies any sense of deliberation or surprise; do not treat a conscious decision as a fixed difference between acabó por renunciar and acabó renunciando.

Compare acabar de + infinitive, which can mean that an action has just happened: Acabo de llegar (I have just arrived). Acabé por llegar describes eventually arriving, not necessarily arriving a moment ago.

Common Mistakes

  • Using acabar por when you mean you have just done something.

    Different Meaning¿Ya te vas? ¡Pero si acabas por llegar!
    ¿Ya te vas? ¡Pero si acabas de llegar!

    Acabas por llegar is a good sentence, but it means you end up arriving after a process. To say you just arrived, use acabar de + infinitive: acabas de llegar.

  • Omitting the preposition 'por'.

    Tras horas de estudio, acabé entender el problema.
    Tras horas de estudio, acabé por entender el problema.

    The preposition 'por' is essential to this construction. Without it, the sentence is grammatically incorrect. An alternative is to use the gerund: 'acabé entendiendo el problema'.
