Past Continuous Tense: Was Were Plus ing, Rules and Examples

Overview

The past continuous tense describes an action that was already in progress at a particular point in the past. Rather than focusing on when an action started or finished, it places the reader inside the middle of the action at a specific moment.

This tense is especially useful in narrative writing and storytelling, where it sets up a scene or background against which other events take place. The past continuous carries the action that was already in progress. The simple past carries the event that interrupted or occurred during it. Learning how these two tenses work together is the central skill of this lesson.

Forming the past continuous follows the same logic as the present continuous, but to be shifts to its past forms: was for singular subjects and were for plural subjects and you. The main verb takes the ing form, and the spelling rules are identical to those in the present continuous lesson.

Forming the Past Continuous Tense

Affirmative Sentences

Use was or were followed by the ing form of the main verb. The choice between was and were follows the same agreement pattern as the simple past of to be.

Negative Sentences

Add not after was or were. The contractions wasn't and weren't are common in everyday use.

Questions

For yes/no questions, move was or were to the front of the sentence before the subject.

Information questions place a question word at the front, followed by was or were and then the subject.

When to Use the Past Continuous Tense

An Action in Progress at a Specific Past Moment

Use the past continuous to describe what was happening at a defined point in the past. The moment can be named explicitly or implied by context.

An Interrupted Action

One of the most common uses is describing an action that was in progress when something else happened. The ongoing action takes the past continuous. The interruption takes the simple past. The conjunctions when and while connect the two clauses.

When introduces the interrupting event in the simple past. While introduces the background action in the past continuous.

Two Simultaneous Actions in the Past

When two ongoing actions were happening at the same time, both take the past continuous form. While is the most natural conjunction here.

Setting the Scene in Narrative Writing

In storytelling, the past continuous establishes atmosphere and background before the main events begin. It creates a still, suspended moment that the simple past then breaks.

Past Continuous vs Simple Past

Both tenses deal with the past, but they describe different relationships to time.

The simple past snaps an action into focus as a completed event. The past continuous stretches it out, placing the reader inside it as it unfolds. When both appear in the same sentence, the past continuous carries the longer background action and the simple past carries the shorter, sharper foreground event.

Common Mistakes to Avoid

Mistake 1: Using the Simple Past Instead of the Past Continuous for Background Actions

When a sentence describes a background action that was in progress before or during another event, the past continuous is needed.

Mistake 2: Using the Past Continuous for a Completed Series of Actions

The past continuous describes one ongoing action, not a sequence of separate completed events. When several things happened one after another, use the simple past.

Mistake 3: Choosing the Wrong Form of To Be

Was belongs to I, he, she, and it. Were belongs to you, we, and they.

Mistake 4: Using Stative Verbs in the Past Continuous Form

Stative verbs are not used in the past continuous. The simple past is required for verbs describing states of mind, emotion, possession, and perception.

Mistake 5: Misplacing When and While

When introduces a short completed action in the simple past. While introduces an ongoing action in the past continuous. Swapping them without adjusting the verb tense produces confusion.

Mistake 6: Forgetting the Ing Form and Using the Base Verb Instead

The past continuous always requires the ing form. Using the base form after was or were is ungrammatical.

Summary

The past continuous describes what was already unfolding at a moment in the past. Use it alongside the simple past to show that one action was in progress when another occurred. Keep stative verbs in the simple past, choose was or were based on the subject, and use when and while with their correct tense combinations.
