Question about Narrative Tenses

Hi Teachers,

I've found these explanations for the Narrative Tenses. My question is about the word 'events' in the Past Progressive. Exactly the one at the end, '... actions that were in progress at the time of events'.

Could you tell me another word for 'events'? To me it seems a bit confusing because before they also use the word 'events'.

The Simple Past

It narrates past events in chronological order. It expresses completed actions at a definitive time in the past. In other words, we use the simple past to talk about the principal events of the story.

The Past Progressive

It is used to describe the situation(s) in which the event(s) of the narrative was/were occurring. In other words, we use the past progressive to describe other events and actions that were in progress at the time of events.

Thanks in advance
