Questions & Answers about Yo iba a dormir, pero el bebé está a punto de llorar.
How does the phrase está a punto de llorar work?
The structure estar a punto de + infinitive means "to be about to" do something. Here, the verb estar is conjugated in the present tense to match the baby (está), followed by the fixed phrase a punto de, and finally the infinitive verb llorar (to cry). It highlights that the action will happen in the immediate future.
Why is iba used here instead of the preterite form fui?
Iba is the imperfect tense of ir (to go). We use iba a + infinitive to talk about past intentions or interrupted plans: things you were going to do. If you said fui a dormir, it would mean you actually went to sleep as a completed past action, which wouldn't make sense with the interruption of the crying baby.
Why is the pronoun yo included at the beginning?
Why is there a de before llorar but an a before dormir?
