The past continuous (or past progressive) is a tense that describes an unfinished action in the past. By unfinished we don’t mean that the action never ended. Rather, the action continued or progressed over a period of time.
To form the past continuous, use was or were and the present participle:
The negative form simply adds not:
We were not dating.
Use the regular form to ask questions:
Were you holding hands?
I was mowing the lawn at the time.
We were drawing penguins.
The past continuous is often used in conjunction with other verbs. Together they relate actions in time:
While we were messaging, Tom’s dad grabbed his phone and threw it out of the window.
Before I went to school, I was reading Asterix and Obelix.
Every day we were conjugating verbs.
It was raining constantly.
Times were changing.
They were learning so many life lessons.
The tomatoes were ripening quickly.
