Past Continuous: Interrupted actions

This grammar pattern uses two different speeds of time. The first speed is the long, continuous background action. The second speed is the quick, sudden event that breaks it. You are basically saying: 'I was busy doing X, then Y happened.' The long action started before the interruption. It usually continues after the interruption too. Or, the interruption might stop the action completely. Think of a grammar traffic light turning red. The green light is your long -ing verb. The red light is your quick Past Simple verb. It is a very common way to speak. Even native speakers use this constantly in daily life.

1. 1Creating this sentence is like building with Lego blocks. You need two parts for the long action. Then you need a connector like when. Finally, you need the short action at the end.
2. 2Start with your subject like I, You, or She.
3. 3Add the helper verb was or were correctly.
4. 4Put -ing at the end of your main verb.
5. 5Use the word when to connect the two parts.
6. 6Finish with a short action in the Past Simple.
7. 7For example: I + was + cooking + when + the phone rang.
8. 8Remember to use was for I, he, she, and it.
9. 9Use were for you, we, and they.
10. 10It is simpler than it looks at first glance.

You use this when describing daily life interruptions. Maybe you were ordering food when you saw a friend. Or you were asking directions when it started to rain. It is perfect for job interviews to explain past tasks. You can say: I was working there when I got promoted. It helps you describe a specific moment in time. Use it when one action 'breaks' into another action. It creates a vivid picture for the person listening. It is like adding color to a black and white photo. Use it to explain why you stopped doing something. I was studying when my laptop died is a classic. We all have those frustrating tech moments, right?

Do not use this for two short actions. If one thing happened after another, use Past Simple. I woke up and then I brushed my teeth is correct. Do not use -ing for 'stative' or 'feeling' verbs. Words like love, know, or hate usually stay simple. You would not say I was knowing the answer. That sounds a bit strange to a native ear. Also, avoid this for permanent facts about the past. If it happened for years, use the Past Simple instead. This pattern is for temporary, ongoing moments that get interrupted. Think of it as a 'snapshot' in a photo album. It is not the whole history book of your life.

The most common mistake is forgetting the helper verb. You cannot just say I cooking when he arrived. You must include was or were every time. Another mistake is putting -ing on both of the verbs. I was walking when it was raining means something else. That shows two long actions happening at the same time. For an interruption, the second verb must be short. Also, watch out for your spelling of the -ing form. Some verbs like run become running with a double letter. Yes, even native speakers mess this up sometimes! Just take your time and check your helper verbs. You will get the hang of it very quickly.

People often confuse this with the Past Simple alone. The Past Simple just says that an action happened. I ate dinner is a simple fact of history. I was eating dinner when you called is a story. It gives context to why you did not answer. It is also different from using while for two long actions. If you say I was cooking while he was cleaning, nobody stops. Both people are just busy in their own little worlds. This interrupted pattern is about the 'clash' of two events. One is the background, and the other is the 'pop'. It is the difference between a movie and a photograph. One has movement and drama, while the other is still.
