Notes & Gotchas
- Used for actions guaranteed to be completed by a future point.
- Conversationally infrequent — most speakers use the simple future or
ir a+ infinitive. - Like all
haberconstructions, the participle stays in masculine singular (terminado, notterminada). - Can also express probability/speculation about the recent past:
Habrá llegado ya(He must have arrived by now).
