The Past Simple form (the second form: go → went) describes finished actions at a specific past time, usually with markers like yesterday, last week, in 2010, ago. Regular verbs add -ed (worked, stopped, studied); the core everyday verbs are irregular and must be memorised. In questions and negatives the auxiliary did takes over the past and the main verb returns to its base form: Did you go? I didn’t go.
