Questions & Answers about Mi jefa cambió la reunión a última hora.

What does the phrase "a última hora" actually mean here?

It means "at the last minute" (very shortly before the meeting was supposed to happen). It describes when the change was made, not the new time of the meeting.

Does "a última hora" mean she moved the meeting to the last time slot of the day?

No. It’s about the timing of the decision (late notice). To say she moved it to the latest slot, you’d use something like: La cambió para última hora de la tarde / del día.

Why is it "última" (feminine)?

Because it agrees with hora, which is a feminine noun. Hence última (not último).

Are there synonyms for "a última hora"?

Yes:

• En el último momento (very common and neutral).
• A último momento (more common in Latin America). In Spain, a última hora and en el último momento are the go‑tos.

Why is the preterite cambió used instead of ha cambiado?
