Explicación: Verbs are divide in 2 groups:

1. irregular verbs: We change the root for example: eat in present and ate in past.

2. regular verbs: We only put ed at the end , for example: start in present and started in past .

*buy is an irregular verb , so we change all for bought

* Did and didn´t are auxilliaries in interrogative and negative form in the past.
