Past perfect: had + participio

"Use had + past participle for an action that happened before another past action."

La regla

had + participio para una acción pasada ANTES de otra acción pasada.

El past perfect marca el orden entre dos eventos pasados: el que ocurrio primero va en past perfect, el segundo en past simple. "When I arrived, the meeting had already started" significa que la reunion empezo ANTES de que yo llegara. Es común con marcadores como by the time, before, after, already, just, never. La forma es invariable: had + participio para todas las personas. En español equivale al pluscuamperfecto: "habia empezado". Los hispanohablantes a veces usan past simple en los dos verbos y se pierde el orden.
