" Function it is Past Perfect Tense"




The past perfect refers to a time earlier than before now. It is used to make it clear that one event happened before another in the past. It does not matter which event is mentioned first - the tense makes it clear which one happened first.
In these examples, Event A is the event that happened first and Event B is the second or more recent event:
Event AEvent B
John had gone outwhen I arrived in the office.
Event AEvent B
had saved my documentbefore the computer crashed.
Event BEvent A
When they arrivedwe had already started cooking.
Event BEvent A
He was very tiredbecause he hadn't slept well.

FORMING THE PAST PERFECT

The Past Perfect tense in English is composed of two parts: the past tense of the verb to have (had) + the past participle of the main verb.

'Just' is used with the past perfect to refer to an event that was only a short time earlier than before now, e.g.
  • The train had just left when I arrived at the station.
  • She had just left the room when the police arrived.
  • had just put the washing out when it started to rain.
