The Simple Background of These Words
English has many irregular verbs. That means they do not follow the normal “-ed” pattern.
For example:

This pattern is old and has been part of English for a very long time.
Many similar verbs change their vowels too:
- ring → rang → rung
- drink → drank → drunk
- swim → swam → swum
So sang and sung follow a common English pattern.
