Futuro perfecto: will have + participio

La regla

Para una acción completada antes de un momento futuro.

"An action completed before a future point in time."

Se forma con will have + participio pasado. Indica que algo ya estara terminado antes de un punto futuro concreto. Marcador tipico: 'by + tiempo futuro' (by Friday, by 2030, by the time...). Diferencia con present perfect: este mira atras desde AHORA; future perfect mira atras desde un FUTURO.
