The Past Continuous Tense is a verb tense used to describe an action that was in progress in the past and was interrupted. It is also used to describe two actions that were taking place at the same time in the past.

Structure:
Subject + was/were + verb-ing

For example:

I was studying for the test when my friend called.
She was walking to the store when it started to rain.

The auxiliary verb “was” is used with singular subjects, and “were” is used with plural subjects. The verb form “-ing” is added to the base form of the verb to indicate continuous action.

The Past Continuous Tense is often used in conjunction with the Simple Past Tense to show that one action was interrupted by another action in the past. For example:

I was studying for the test when my friend called. (The action of studying was in progress and was interrupted by the call from my friend.)

The key words for the Past Continuous Tense include the auxiliary verbs “was” and “were” and the “-ing” form of verbs, which indicate continuous action in the past. Some common key words that signal the use of the Past Continuous Tense include:
