Questions & Answers about Yo dormía cuando sonó el teléfono.

Why use the imperfect tense for dormía but the indefinido (preterite) for sonó?

This sentence shows a classic pattern: an ongoing action interrupted by a sudden event. We use the imperfect for dormía because it sets the background scene (what was already happening). We use the indefinido for sonó because it is a completed, one-time action that interrupted the sleep.

Why is the word order sonó el teléfono instead of el teléfono sonó?

In Spanish, it is very common to put the subject (el teléfono) after the verb, especially for actions like appearing, arriving, or making a sudden noise. You could say el teléfono sonó, but sonó el teléfono sounds much more natural to native speakers.

Is the word yo strictly necessary here?

No, you could just drop it and say Dormía cuando sonó el teléfono. However, because the imperfect ending -ía is exactly the same for I, he, she, and it (yo dormía, él dormía), speakers often include yo to make it perfectly clear who was sleeping.

Could I say estaba durmiendo instead of dormía?

Yes, you absolutely can! Estaba durmiendo uses the past continuous to mean I was sleeping. In Spanish, the imperfect (dormía) and the past continuous (estaba durmiendo) can often be used interchangeably to describe an ongoing background action in the past.
