Past simple (= simple past)

You use the past simple:

To indicate that something happened in the past and is ready.
Often there is a time indicator in the sentence, like: yesterday, last week, two months ago, when I was younger, in 1995.

You form the past simple by adding '-ed' after the verb

Examples:

 

You form a question by using did + whole verb.
A negation is made by using didn't + whole verb.

Spelling:
If the verb ends on a consonant (medeklinker) + '-y', the '-y' changes in -ie:

But: when the verb ends on a vowel (klinker) + '-y', nothing changes; just add '-ed' after the '-y'

 

If the verb already ends on '-e', simply add '-d': 

 

NB: double the last consonant (medeklinker) if there's a vowel (klinker) before it:
