❓ Frequently Asked Questions (FAQ)

Q1: What is the main difference between Past Simple and Past Continuous?

Past Simple states a completed past event ("I ate dinner"). Past Continuous emphasizes an action IN PROGRESS at a past moment ("I was eating dinner when the phone rang").

Q2: Can "while" be used with Past Simple?

Generally no. "While" indicates duration, so it is followed by Past Continuous ("while I was driving"). "When" can be followed by either Past Simple or Past Continuous.
